Green Thumb

Who better than a county agent—a sort of local government functionary whose job it is to aid farmers with a variety of problems—to deal with intelligent plants from space?

“Green Thumb” was submitted to H. L. Gold of Galaxy Science Fiction in February 1954. Gold purchased it for three hundred dollars, and the story was published in the July 1954 issue of the magazine. The story is only one of a number of Simak stories that displayed the intrigue he felt for the concept of plant intelligence.

I had come back from lunch and was watching the office while Millie went out to get a bite to eat. With my feet up on the desk in a comfortable position, I was giving considerable attention to how I might outwit a garbage-stealing dog.

The dog and I had carried on a feud for months and I was about ready to resort to some desperate measures.

I had blocked up the can with heavy concrete blocks so he couldn’t tip it over, but he was a big dog and could stand up and reach down into the can and drag all the garbage out. I had tried putting a heavy weight on the lid, but he simply dragged it off and calmly proceeded with his foraging. I had waited up and caught him red-handed at it and heaved some rocks and whatever else was handy at him, but he recognized tactics such as these for what they were and they didn’t bother him. He’d come back in half an hour, calm as ever.

I had considered setting a light muskrat trap on top of the garbage so that, when he reached down into the can, he’d get his muzzle caught. But if I did that, sure as hell I’d forget to take it out some Tuesday morning and the garbage man would get caught instead. I had toyed with the idea of wiring the can so the dog would get an electric shock when he came fooling around. But I didn’t know how to go about wiring it and, if I did, ten to one I’d fix it up so I’d electrocute him instead of just scaring him off, and I didn’t want to kill him.

I like dogs, you understand. That doesn’t mean I have to like all dogs, does it? And if you had to scrape up garbage every morning, you’d be just as sore at the mutt as I was.

While I was wondering if I couldn’t put something in a particularly tempting bit of garbage that would make him sick and still not kill him, the phone rang.

It was old Pete Skinner out on Acorn Ridge.

“Could you come out?” he asked.

“Maybe,” I said. “What you got?”

“I got a hole out in the north forty.”

“Sink-hole?”

“Nope. Looks like someone dug it out and carried off the dirt.”

“Who would do that, Pete?”

“I don’t know. And that ain’t all of it. They left a pile of sand beside the hole.”

“Maybe that’s what they dug out of the hole.”

“You know well enough,” said Pete, “that I haven’t any sandy soil. You’ve run tests enough on it. All of mine is clay.”

“I’ll be right out,” I told him.

A county agent gets some funny calls, but this one topped them all. Hog cholera, corn borers, fruit blight, milk production records—any of these would have been down my alley. But a hole in the north forty?

And yet, I suppose I should have taken it as a compliment that Pete called me. When you’ve been a county agent for fifteen years, a lot of farmers get to trust you and some of them, like Pete, figure you can straighten out any problem. I enjoy a compliment as much as anybody. It’s the headaches that go with them that I don’t like.

When Millie came back, I drove out to Pete’s place, which is only four or five miles out of town.

Pete’s wife told me that he was up in the north forty, so I went there and found not only Pete, but some of his neighbors. All of them were looking at the hole and doing a lot of talking. I never saw a more puzzled bunch of people.

The hole was about 30 feet in diameter and about 35 feet deep, an almost perfect cone—not the kind of hole you’d dig with a pick and shovel. The sides were cut as clean as if they’d been machined, but the soil was not compressed, as it would have been if machinery had been used.

The pile of sand lay just a short distance from the hole. Looking at it, I had the insane feeling that, if you shoveled that sand into the hole, it would exactly fit. It was the whitest sand I’ve ever seen and, when I walked over to the pile and picked up some of it, I saw that it was clean. Not just ordinary clean, but absolutely clean—as though laundered grain by grain.

I stood around for a while, like the rest of them, staring at the hole and the pile of sand and wishing I could come up with some bright idea. But I wasn’t able to. There was the hole and there was the sand. The topsoil was dry and powdery and would have shown wheel marks or any other kind it there’s been any. There weren’t.

I told Pete maybe he’d better fence in the whole business, because the sheriff or somebody from the state, or even the university, might want to look it over. Pete said that was a good idea and he’d do it right away.

I went back to the farmhouse and asked Mrs. Skinner to give me a couple of fruit jars. One of them I filled with a sample from the sand pile and the other with soil from the hole, being careful not to jolt the walls.

By this time, Pete and a couple of the neighbors had gotten a wagonload of fence posts and some wire and were coming out to the field. I waited and helped unload the posts and wire, then drove back to the office, envying Pete. He was satisfied to put up the fence and let me worry about the problem.

I found three fellows waiting for me. I gave Millie the fruit jars and asked her to send them right away to the Soils Bureau at the State Farm Campus. Then I settled down to work.

Other people drifted in and it was late in the afternoon before I could call up the Soils Bureau and tell them I wanted the contents of the two jars analyzed. I told them a little of what had happened, although not all of it for, when you tried to put it into words, it sounded pretty weird.

“Banker Stevens called and asked if you’d drop by his place on your way home,” Millie told me.

“What would Stevens want with me?” I asked. “He isn’t a farmer and I don’t owe him any money.”

“He grows fancy flowers,” said Millie.

“I know that. He lives just up the street from me.”

“From what I gathered, something awful happened to them. He was all broken up.”

So, on the way home, I stopped at the Stevens place. The banker was out in the yard, waiting for me. He looked terrible. He led me around to the big flower garden in the back and never have I seen such utter devastation. In that whole area, there wasn’t a single plant alive. Every one of them had given up the ghost and was lying wilted on the ground.

“What could have done it, Joe?” asked Stevens and, the way he said it, I felt sorry for him.

After all, those flowers were a big thing in his life. He’d raised them from special seed and he’d babied them along, and for anybody who is crazy about flowers, I imagine they were tops.

“Someone might have used some spray on them,” I said. “Almost any kind of spray, if you don’t dilute it enough, would kill them.”

Out in the garden, I took a close look at the dead flowers, but nowhere could I see any sign of the burning from too strong a spray.

Then I saw the holes, at first only two or three of them, then, as I went on looking, dozens of them. They were all over the garden, about an inch in diameter, for all the world as if someone had taken a broomstick and punched holes all over the place. I got down on my knees and could see that they tapered, the way they do when you pull weeds with big taproots out of the ground.

“You been pulling weeds?” I asked.

“Not big ones like that,” said the banker. “I take good care of those flowers, Joe. You know that. Keep them weeded and watered and cultivated and sprayed. Put just the right amount of commercial fertilizer in the soil. Try to keep it at top fertility.”

“You should use manure. It’s better than all the commercial fertilizer you can buy.”

“I don’t agree with you. Tests have proved …”

It was an old argument, one that we fought out each year. I let him run on, only half listening to him, while I picked up some of the soil and crumbled it. it was dead soil. You could feel that it was. It crumbled at the lightest touch and was dry, even when I dug a foot beneath the surface.

“You water this bed recently?” I asked.

“Last evening,” Stevens said.

“When did you find the flowers like this?”

“This morning. They looked fine last night. And now—” he blinked fast.

I asked him for a fruit jar and filled it with a sample of the soil.

“I’ll send this in and see if there’s anything wrong with it,” I said.

A bunch of dogs were barking at something in the hedge in front of my place when I got home. Some of the dogs in the neighborhood are hell on cats. I parked the car and picked up an old hoe handle and went out to rescue the cat they seemed to have cornered.

They scattered when they saw me coming and I started to look in the hedge for the cat. There wasn’t any and that aroused my curiosity and I wondered what the dogs could have been barking at. So I went hunting.

And I found it.

It was lying on the ground, close against the lower growth of the hedge, as if it had crawled there for protection.

I reached in and pulled it out—a weed of some sort, about five feet tall, and with a funny root system. There were eight roots, each about an inch in diameter at the top and tapering to a quarter inch or so. They weren’t all twisted up, but were sort of sprung out, so that there were four to the side, each set of four in line. I looked at their tips and I saw that the roots were not broken off, but ended in blunt, strong points.

The stalk, at the bottom, was about as thick as a man’s fist. There were four main branches covered with thick, substantial, rather meaty leaves; but the last foot of the branches was bare of leaves. At the top were several flower or seed pouches, the biggest of them the size of an old-fashioned coffee mug.

I squatted there looking at it. The more I looked, the more puzzled I became. As a county agent, you have to know quite a bit about botany and this plant was like none I had seen before.

I dragged it across the lawn to the toolshed back of the garage and tossed it in there, figuring that after supper I’d have a closer look at it.

I went in the house to get my evening meal ready and decided to broil a steak and fix up a bowl of salad.

A lot of people in town wonder at my living in the old homestead, but I’m used to the house and there seemed to be no sense in moving somewhere else when all it costs me is taxes and a little upkeep. For several years before Mother died, she had been quite feeble and I did all the cleaning and helped with the cooking, so I’m fairly handy at it.

After I washed the dishes, I read what little there was to read in the evening paper and then looked up an old text on botany, to see if I could find anything that might help identify the plant.

I didn’t find anything and, just before I went to bed, I got a flashlight and went out, imagining, I suppose, that I’d find the weed somehow different than I remembered it.

I opened the door of the shed and flashed the light where I’d tossed the weed on the floor. At first, I couldn’t see it, then I heard a leafy rustling over in one corner and I turned the light in that direction.

The weed had crawled over to one corner and it was trying to get up, its stem bowed out—the way a man would arch his back—pressing against the wall of the shed.

Standing there with my mouth open, watching it try to raise itself erect, I felt horror and fear. I reached out to the corner nearest the door and snatched up an axe.

If the plant has succeeded in getting up, I might have chopped it to bits. But, as I stood there, I saw the thing would never make it. I was not surprised when it slumped back on the floor.

What I did next was just as unreasoning and instinctive as reaching for the axe.

I found an old washtub and half filled it with water. Then I picked up the plant—it had a squirmish feel to it, like a worm—stuck its roots into the water, and pushed the tub back against the wall, so the thing could be braced upright.

I went into the house and ransacked a couple of closets until I found the sunlamp I’d bought a couple of years back, to use when I had a touch of arthritis in my shoulder. I rigged up the lamp and trained it on the plant, not too close. Then I got a big shovelful of dirt and dumped it in the tub.

And that, I figured, was about all I could do. I was giving the plant water, soil-food and simulated sunlight. I was afraid that, if I tried a more fancy treatment, I might kill it, for I hadn’t any notion of what conditions it might be used to.

Apparently I handled it right. It perked up considerably and, as I moved about, the coffee-cup-sized pod on the top kept turning, following every move I made.

I watched it for a while and moved the sunlamp back a little, so there’d be no chance of scorching it, and went back into the house.

It was then that I really began to get bone-scared. I had been frightened out in the shed, of course, but that had been shock. Now, thinking it over, I began to understand more clearly what sort of creature I’d found underneath the hedge. I remember I wasn’t yet ready to say it out loud, but it seemed probable that my guest was an alien intelligence.

I did some wondering about how it had gotten here and if it had made the holes in Banker Stevens’ flowerbed and also if it could have had anything to do with the big hole out in Pete Skinner’s north forty.

I sat around, arguing with myself, for a man just does not go prowling around in his neighbor’s garden after midnight.

But I had to know.

I walked up the alley to the back of the Stevens house and sneaked into the garden. Shielding the flashlight with my hat, I had another look at the holes in the ruined flowerbed. I wasn’t too surprised when I saw that they occurred in series of eight, four to the side—exactly the kind of holes the plant back in my tool-shed would make if it sank its roots into the ground.

I counted at least eleven of those eight-in-line sets of holes and I’m sure that there were more. But I didn’t want to stick around too long, for fear Banker Stevens might wake up and ask questions.

So I went back home, down the alley, and was just in time to catch that garbage-stealing dog doing a good job on the can. He had his head stuck clear down into it and I was able to sneak up behind him. He heard me and struggled to get out, but he’d jammed himself into the can. Before he could get loose, I landed a good swift kick where it did maximum good. He set some kind of canine speed record in getting off the premises, I imagine.

I went to the toolshed and opened the door. The tub half full of muddy water was still there and the sunlamp was still burning—but the plant was gone. I looked all over the shed and couldn’t find it. So I unplugged the sunlamp and headed for the house.

To be truthful, I was a little relieved that the plant had wandered off.

But when I rounded the corner of the house, I saw it hadn’t. It was in the window box, and the geraniums I had nursed all spring were hanging limply over the side of the box.

I stood there and looked at it and had the feeling that it was looking back at me.

And I remembered that not only had it had to travel from the toolshed to the house and then climb into the window box, but it had had to open the toolshed door and close it again.

It was standing up, stiff and straight, and appeared to be in the best of health. It looked thoroughly incongruous in the window box—as if a man had grown a tall stalk of corn there, although it didn’t look anything like a stalk of corn.

I got a pail of water and poured it into the window box. Then I felt something tapping me on the head and looked up. The plant had bent over and was patting me with one of its branches. The modified leaf at the end of the branch has spread itself out to do the patting and looked something like a hand.

I went into the house and up to bed and the main thing I was thinking about was that, if the plant got too troublesome or dangerous, all I had to do was mix a strong dose of commercial fertilizer or arsenic, or something just as deadly, and water it with the mixture.

Believe it or not, I went to sleep.

Next morning I got to thinking that maybe I should repair the old greenhouse and put my guest in there and be sure to keep the door locked. It seemed to be reasonably friendly and inoffensive, but I couldn’t be sure, of course.

After breakfast I went out into the yard to look for it, with the idea of locking it in the garage for the day, but it wasn’t in the window box, or anywhere that I could see. And since it was Saturday, when a lot of farmers came to town, with some of them sure to be dropping in to see me, I didn’t want to be late for work.

I was fairly busy during the day and didn’t have much time for thinking or worrying. But when I was wrapping up the sample of soil from the banker’s garden to send to the Soils Bureau, I wondered if maybe there wasn’t someone at the university I should notify. I also wondered about letting someone in Washington know, except I didn’t have the least idea whom to contact, or even which department.

Coming home that evening, I found the plant anchored in the garden, in a little space where the radishes and lettuce had been. The few lettuce plants still left in the ground were looking sort of limp, but everything else was all right. I took a good look at the plant. It waved a couple of its branches at me—and it wasn’t the wind blowing them, for there wasn’t any wind—and it nodded its coffee-cup pod as if to let me know it recognized me. But that was all it did.

After supper, I scouted the hedge in front of the house and found two more of the plants. Both of them were dead.

My next-door neighbors had gone to a movie, so I scouted their place, too, and found four more of the plants, under bushes and in corners where they had crawled away to die.

I wondered whether it might not have been the plant I’d rescued that the dogs had been barking at the night before. I felt fairly sure it was. A dog might be able to recognize an alien being where a man would be unable to.

I counted up. At least seven of the things had picked out Banker Stevens’ flowerbed for a meal and the chemical fertilizer he used had killed all but one of them. The sole survivor, then, was out in the garden, killing off my lettuce.

I wondered why the lettuce and geraniums and Stevens’ flowers had reacted as they did. It might be that the alien plants produced some sort of poison, which they injected into the soil to discourage other plant life from crowding their feeding grounds. That was not exactly far-fetched. There are trees and plants on Earth that accomplish the same thing by various methods. Or it might be that the aliens sucked the soil so dry of moisture and plant-food that the other plants simply starved to death.

I did some wondering on why they’d come to Earth at all and why some of them had stayed. If they had travelled from some other planet, they must have come in a ship, so that hole out in Pete’s north forty might have been where they stopped to replenish their food supply, dumping the equivalent of garbage beside the hole.

And what about the seven I had counted?

Could they have jumped ship? Or gone on shore leave and run into trouble, the way human sailors often do?

Maybe the ship had searched for the missing members of the party, had been unable to find them, and had gone on. If that were so, then my own plant was a marooned alien. Or maybe the ship was still hunting.

I wore myself out, thinking about it, and went to bed early, but lay there tossing for a long time. Then, just as I was falling asleep, I heard the dog at the garbage can. You’d think after what had happened to him the night before, that he’d have decided to skip that particular can, but not him. He was rattling and banging it around, trying to tip it over.

I picked a skillet off the stove and opened the back door. I got a good shot at him, but missed him by a good ten feet. I was so sore that I didn’t even go out to pick up the skillet, but went back to bed.

It must have been several hours later that I was brought straight up in bed by the terror-stricken yelping of a dog. I jumped out and ran to the window. It was a bright moonlit night and the dog was going down the driveway as if the devil himself were after him. Behind him sailed the plant. It had wrapped one of its branches around his tail and the other three branches were really giving him a working over.

They went up the street out of sight and, for a long time after they disappeared, I could hear the dog still yelping. Within a few minutes, I saw the plant coming up the gravel, walking like a spider on its eight roots.

It turned off the driveway and planted itself beside a lilac bush and seemed to settle down for the night. I decided that if it wasn’t good for anything else, the garbage can would be safe, at least. If the dog came back again, the plant would be waiting to put the bee on him.

I lay awake for a long time, wondering how the plant had known I didn’t want the dog raiding the garbage. It probably had seen—if that is the proper word—me chase him out of the yard.

I went to sleep with the comfortable feeling that the plant and I had finally begun to understand each other.

The next day was Sunday and I started working on the greenhouse, putting it into shape so I could cage up the plant. It had found itself a sunny spot in the garden and was imitating a large and particularly ugly weed I’d been too lazy to pull out.

My next-door neighbor came over to offer free advice, but he kept shifting uneasily and I knew there was something on his mind.

Finally he came out with it. “Funny thing—Jenny swears she saw a big plant walking around in your yard the other day. The kid saw it, too, and he claims it chased him.” He tittered a little, embarrassed. “You know how kids are.”

“Sure,” I said.

He stood around a while longer and gave me some more advice, then went across the yard and home.

I worried about what he had told me. If the plant really had taken to chasing kids, there’d be hell to pay.

I worked at the greenhouse all day long, but there was a lot to do, for it had been out of use ten years or more, and by nightfall I was tuckered out.

After supper, I went out on the back stoop and sat on the steps, watching the stars. It was quiet and restful.

I hadn’t been there more than fifteen minutes when I heard a rustling. I looked around and there was the plant, coming up out of the garden, walking along on its roots.

It sort of squatted down beside me and the two of us just sat there, looking at the stars. Or, at least, I looked at them. I don’t actually know if the plant could see. If it couldn’t, it had some other faculty that was just as good as sight. We just sat there.

After a while, the plant moved one of its branches over and took hold of my arm with that handlike leaf. I tensed a bit, but its touch was gentle enough and I sat still, figuring that if the two of us were to get along, we couldn’t start out by flinching away from one another.

Then, so gradually that at first I didn’t notice it, I began to perceive a sense of gratitude, as if the plant might be thanking me. I looked around to see what it was doing and it wasn’t doing a thing, just sitting there as I was, but with its “hand” still on my arm.

Yet in some way, the plant was trying to make me understand that it was grateful to me for saving it.

It formed no words, you understand. Other than rustling its leaves, it couldn’t make a sound. But I understood that some system of communication was in operation. No words, but emotion—deep, clear, utterly sincere emotion.

It eventually got a little embarrassing, this non-stop gratitude.

“Oh, that’s all right,” I said, trying to put an end to it. “You would have done as much for me.”

Somehow, the plant must have sensed that its thanks had been accepted, because the gratitude wore off a bit and something else took over—a sense of peace and quiet.

The plant got up and started to walk off and I called out to it, “Hey, Plant, wait a minute!”

It seemed to understand that I had called it back, for it turned around. I took it by a branch and started to lead it around the boundaries of the yard. If this communication business was going to be any good, you see, it had to go beyond the sense of gratitude and peace and quiet. So I led the plant all the way around the yard and I kept thinking at it as hard as I could, telling it not to go beyond that perimeter.

By the time I’d finished, I was wringing wet with effort. But, finally, the plant seemed to be trying to say okay. Then I built up a mental image of it chasing a kid and I shook a mental finger at it. The plant agreed. I tried to tell it not to move around the yard in daylight, when people would be able to see it. Whether the concept was harder or I was getting tired, I don’t know, but both the plant and I were limp when it at last indicated that it understood.

Lying in bed that night, I thought a lot about this problem of communication. It was not telepathy, apparently, but something based on mental pictures and emotions.

But I saw it as my one chance. If I could learn to converse, no matter how, and the plant could learn to communicate something beyond abstracts to me, it could talk to people, would be acceptable and believable, and the authorities might be willing to recognize it as an intelligent being. I decided that the best thing to do would be to acquaint it with the way we humans lived and try to make it understand why we lived that way. And since I couldn’t take my visitor outside the yard, I’d have to do it inside.

I went to sleep, chuckling at the idea of my house and yard being a classroom for an alien.

The next day I received a phone call from the Soils Bureau at the university.

“What kind of stuff is this you’re sending us?” the man demanded.

“Just some soil I picked up,” I said. “What’s wrong with it?”

“Sample One is all right. It’s just common, everyday Burton County soil. But Sample Two, that sand—good God, man, it has gold dust and flakes of silver and some copper in it! All of it in minute particles, of course. But if some farmer out your way has a pit of that stuff, he’s rich.”

“At the most, he has twenty-five or thirty truckloads of it.”

“Where’d he get it? Where’d it come from?”

I took a deep breath and told him all I knew about the incident out at Pete’s north forty.

He said he’d be right out, but I caught him before he hung up and asked him about the third sample.

“What was he growing on that ground?” the man asked baffledly. “Nothing I know of could suck it that clean, right down to the bare bone! Tell him to put in a lot of organic material and some lime and almost everything else that’s needed in good soil, before he tries to use it.”

The Soils people came out to Pete’s place and they brought along some other men from the university. A little later in the week, after the papers had spelled out big headlines, a couple of men from Washington showed up. But no one seemed able to figure it out and they finally gave up. The newspapers gave it a play and dropped it as soon as the experts did.

During that time, curiosity seekers flocked to the farm to gape at the hole and the pile of sand. They had carried off more than half the sand and Pete was madder than hell about the whole business.

“I’m going to fill in that hole and forget all about it,” he told me, and that was what he did.

Meanwhile, at home, the situation was progressing. Plant seemed to understand what I had told him about not moving out of the yard and acting like a weed during the daytime and leaving kids alone. Everything was peaceable and I got no more complaints. Best of all, the garbage-stealing dog never showed his snout again.

Several times, during all the excitement out at Pete’s place, I had been tempted to tell someone from the university about Plant. In each case, I decided not to, for we weren’t getting along too well in the talk department.

But in other ways we were doing just fine.

I let Plant watch me while I took an electric motor apart and then put it together again, but I wasn’t too sure he knew what it was all about. I tried to show him the concept of mechanical power and I demonstrated how the motor would deliver that power and I tried to tell him what electricity was. But I got all bogged down with that, not knowing too much about it myself. I don’t honestly think Plant got a thing out of that electric motor.

With the motor of the car, though, we were more successful. We spent one whole Sunday dismantling it and then putting it back together. Watching what I was doing, Plant seemed to take a lot of interest in it.

We had to keep the garage door locked and it was a scorcher of a day and, anyhow, I’d much rather spend a Sunday fishing than tearing down a motor. I wondered a dozen times if it was worth it, if there might not be easier ways to teach Plant the facts of our Earth culture.

I was all tired out and failed to hear the alarm and woke up an hour later than I should. I jumped into my clothes, ran out to the garage, unlocked the door and there was Plant. He had parts from that motor strewn all over the floor and he was working away at it, happy as a clam. I almost took an axe to him, but I got hold of myself in time. I locked the door behind me and walked to work.

All day, I wondered how Plant had gotten into the garage. Had he sneaked back in the night before, when I wasn’t looking, or had he been able to pick the lock? I wondered, too, what sort of shape I’d find the car in when I got home. I could just see myself working half the night, putting it back together.

I left work a little early. If I had to work on the car, I wanted an early start.

When I got home, the motor was all assembled and Plant was out in the garden, acting like a weed. Seeing him there, I realized he knew how to unlock the door, for I’d locked it when I left that morning.

I turned on the ignition, making bets with myself that it wouldn’t start. But it did. I rode around town a little to check it and there wasn’t a thing wrong with it.

For the next lesson, I tried something simpler. I got my carpentry tools and showed them to Plant and let him watch me while I made a bird house. Not that I needed any more bird houses. The place already crawled with them. But it was the easiest, quickest thing I could think of to show Plant how we worked in wood.

He watched closely and seemed to understand what was going on, all right, but I detected a sadness in him. I put my hand on his arm to ask him what was the matter.

All that I got was a mournful reaction.

It bewildered me. Why should Plant take so much interest in monkeying around with a motor and then grieve at the making of a bird house? I didn’t get it figured out until a few days later, when Plant saw me picking a bouquet of flowers for the kitchen table.

And then it hit me.

Plant was a plant and flowers were plants and so was lumber, or at least lumber at one time had been a plant. And I stood there, with the bouquet dangling in my hand and Plant looking at me, and I thought of all the shocks he had in store when he found out more about us—how we slaughtered our forests, grew plants for food and clothing, squeezed or boiled drugs from them.

It was just like a human going to another planet, I realized, and finding that some alien life form grew humans for food.

Plant didn’t seem to be sore at me nor did he shrink from me in horror. He was just sad. When he got sad, he was the saddest-looking thing you could possibly imagine. A bloodhound with a hangover would have looked positively joyous in comparison.

If we ever had gotten to the point where we could have really talked—about things like ethics and philosophy, I mean—I might have learned just how Plant felt about our plant-utilizing culture. I’m sure he tried to tell me, but I couldn’t understand much of what he was driving at.

We were sitting out on the steps one night, looking at the stars. Earlier, Plant had been showing me his home planet, or it may have been some of the planets he had visited. I don’t know. All I could get were fuzzy mental pictures and reactions. One place was hot and red, another blue and cold. There was another that had all the colors of the rainbow and a cool, restful feel about it, as if there might have been gentle winds and fountains and birdsongs in the twilight.

We had been sitting there for quite a while when he put his hand back on my arm again and he showed me a plant. He must have put considerable effort into getting me to visualize it, for the image was sharp and clear. It was a scraggy, rundown plant and it looked even sadder than Plant looked when he got sad, if that is possible. When I started feeling sorry for it, he began to think of kindness and, when he thought of things like kindness and sadness and gratitude and happiness, he could really pour it on.

He had me thinking such big, kindly thoughts, I was afraid that I would burst. While I sat there, thinking that way, I saw the plant begin to perk up. It grew and flowered and was the most beautiful thing I had ever seen. It matured its seeds and dropped them. Swiftly, little plants sprang from the seeds and they were healthy and full of ginger, too.

I mulled that one over several days, suspecting I was crazy for even thinking what I did. I tried to shrug it off, but it wouldn’t shrug. It gave me an idea.

The only way I could get rid of it was to try it out.

Out in back of the toolshed was the sorriest yellow rose in town. Why it clung to life, year after year, I could never figure out. It had been there ever since I was a boy. The only reason it hadn’t been dug up and thrown away long ago was that no one had ever needed the ground it was rooted in.

I thought, if a plant ever needed help, that yellow rose was it.

So I sneaked out back of the toolshed, making sure that Plant didn’t see me, and stood in front of that yellow rose. I began to think kindly thoughts about it, although God knows it was hard to think kindly toward such a wretched thing. I felt foolish and hoped none of the neighbors spotted me, but I kept at it. I didn’t seem to accomplish much to start with, but I went back, time after time. In a week or so, I got so that I just naturally loved that yellow rose to pieces.

After four or five days, I began to see some change in it. At the end of two weeks, it had developed from a scraggy, no-account bush to one that any rose fancier would have been proud to own. It dropped its bug-chewed leaves and grew new ones that were so shiny, they looked as if they were waxed. Then it grew big flower buds and, in no time at all, was a blaze of yellow glory.

But I didn’t quite believe it. In the back of my mind, I figured that Plant must have seen me doing it and helped along a bit. So I decided to test the process again where he couldn’t interfere.

Millie had been trying for a couple of years to grow an African violet in a flower pot at the office. By this time, even she was willing to admit it was a losing battle. I had made a lot of jokes about the violet and, at times, Millie had been sore at me about it. Like the yellow rose, it was a hard-luck plant. The bugs ate it. Millie forgot to water it. It got knocked onto the floor. Visitors used it for an ashtray.

Naturally, I couldn’t give it the close, intensive treatment I’d given the rose, but I made a point to stop for a few minutes every day beside the violet and think good thoughts about it and, in a couple of weeks, it perked up considerably. By the end of the month, it had bloomed for the first time in its life.

Meanwhile, Plant’s education continued.

At first, he’d balked at entering the house, but finally trusted me enough to go in. He didn’t spend much time there, for the house was too full of reminders that ours was a plant-utilizing culture. Furniture, clothing, cereal, paper—even the house itself—were all made of vegetation. I got an old butter tub and filled it with soil and put it in one corner of the dining room, so he could eat in the house if he wanted to, but I don’t remember that he even once took a snack out of that tub.

Although I didn’t admit it then, I knew that what Plant and I had tried to do had been a failure. Whether someone else might have done better, I don’t know. I suspect he might have. But I didn’t know how to go about getting in touch and I was afraid of being laughed at. It’s a terrible thing, our human fear of ridicule.

And there was Plant to consider, too. How would he take being passed on to someone else? I’d screw up my courage to do something about it, and then Plant would come up out of the garden and sit beside me on the steps, and we’d talk—not about anything that mattered, really, but about happiness and sadness and brotherhood, and my courage would go glimmering and I’d have to start all over again.

I’ve since thought how much like two lost children we must have been, strange kids raised in different countries, who would have liked to play together, except neither knew the rules for the other’s games or spoke the other’s language.

I know … I know. According to common sense, you begin with mathematics. You show the alien that you know two and two are four. Then you draw the Solar System and show him the Sun on the diagram and then point to the Sun overhead and you point to Earth on the diagram, then point to yourself. In this way, you demonstrate to him that you know about the Solar System and about space and the stars and so on.

Then you hand him the paper and the pencil.

But what if he doesn’t know mathematics? What if the two-plus-two-makes-four routine doesn’t mean a thing to him? What if he’s never seen a drawing? What if he can’t draw—or see or hear or feel or think the way you do?

To deal with an alien, you’ve got to get down to basics.

And maybe math isn’t basic.

Maybe diagrams aren’t.

In that case, you have to search for something that is.

Yet there must be certain universal basics.

I think I know what they are.

That, if nothing else, Plant taught me.

Happiness is basic. And sadness is basic. And gratitude, in perhaps a lesser sense. Kindness, too. And perhaps hatred—although Plant and I never dealt in that.

Maybe brotherhood. For the sake of humanity, I hope so.

But kindness and happiness and brotherhood are awkward tools to use in reaching specific understanding, although in Plant’s world they may not be.

It was getting on toward autumn and I was beginning to wonder how I’d take care of Plant during the winter months.

I could have kept him in the house, but he hated it there.

Then, one night, we were sitting on the back steps, listening to the first crickets of the season.

The ship came down without a sound. I didn’t see it until it was about at treetop level. It floated down and landed between the house and toolshed.

I was startled for a moment, but not frightened, and perhaps not too surprised. In the back of my head, I’d wondered all the time, without actually knowing it, whether Plant’s pals might not ultimately find him.

The ship was a shimmery sort of thing, as if it might not have been made of metal and was not really solid. I noticed that it had not really landed, but floated a foot or so above the grass.

Three other Plants stepped out and the oddest part of it was that there wasn’t any door. They just came out of the ship and the ship closed behind them.

Plant took me by the arm and twitched it just a little, to make me understand he wanted me to walk with him to the ship. He made little comforting thoughts to try to calm me down.

And all the time that this was going on, I could sense the talk between Plant and those other three—but just grasping the fringe of the conversation, barely knowing there was talk, not aware of what was being said.

And then, while Plant stood beside me, with his hand still on my arm, those other plants walked up. One by one, each took me by the other arm and stood facing me for a moment and told me thanks and happiness.

Plant told me the same, for the last time, and then the four of them walked toward the ship and disappeared into it. The ship left me standing there, watching it rise into the night, until I couldn’t see it any longer.

I stood there for a long time, staring up into the sky, with the thanks and happiness fading and loneliness beginning to creep in.

I knew that, somewhere up there, was a larger ship, that in it were many other Plants, that one of them had lived with me for almost six months and that others of them had died in the hedges and fence corners of the neighborhood. I knew also that it had been the big ship that had scooped out the load of nutritious soil from Pete Skinner’s field.

Finally, I stopped looking at the sky. Over behind the toolshed I saw the whiteness of the yellow rose in bloom and once again I thought about the basics.

I wondered if happiness and kindness, perhaps even emotions that we humans do not know, might not be used on Plant’s world as we use the sciences.

For the rose bush had bloomed when I thought kindly thoughts of it. And the African violet had found a new life in the kindness of a human.

Startling as it may seem, foolish as it may sound, it is not an unknown phenomenon. There are people who have the knack of getting the most out of a flowerbed or a garden. And it is said of these people that they have green thumbs.

May it not be that green thumbness is not so much concerned with skill or how much care is taken of a plant, as with the kindliness and the interest of the person tending it?

For eons, the plant life of this planet has been taken for granted. It is simply there. By and large, plants are given little affection. They are planted or sown. They grow. In proper season, they are harvested.

I sometimes wonder if, as hunger tightens its grip upon our teeming planet, there may not be a vital need for the secret of green thumbness.

If kindness and sympathy can cause a plant to produce beyond its normal wont, then shouldn’t we consider kindness as a tool to ward off Earth’s hunger? How much more might be produced if the farmer loved his wheat?

It’s silly, of course, a principle that could not gain acceptance.

And undoubtedly it would not work—not in a plant-utilizing culture.

For how could you keep on convincing a plant that you feel kindly toward it when, season after season, you prove that your only interest in it is to eat it or make it into clothing or chop it down for lumber?

I walked out back of the shed and stood beside the yellow rose, trying to find the answer. The yellow rose stirred, like a pretty woman who knows she’s being admired, but no emotion came from it.

The thanks and happiness were gone. There was nothing left but the loneliness.

Damned vegetable aliens—upsetting a man so he couldn’t eat his breakfast cereal in peace!
