Partial shade
Average soil
Pastel-colored flowers — baby blues, pale pinks, lovely lilacs, and mellow yellows — are positively made for the shade. Their light faces stand out well against the gloom, adding welcome bits of brightness all through the growing season. With the addition of some white-marked leaves for extra zip and rich green leaves for contrast, you have all the ingredients for a shade garden that is sure to please.

Spring: Pastels are a classic color range for spring, and this garden offers them in abundance. ‘Etain’ viola is generally the first to bloom, with fragrant, soft yellow flowers that are edged with lavender-purple. ‘Stairway to Heaven’ creeping Jacob’s ladder joins in soon after, with clusters of lightly scented, light blue flowers over white-and-green leaves that are heavily blushed with pink. And by late spring — if not earlier — the pale pink blossoms of ‘Biokovo’ hardy geranium open, too. ‘Camelot Rose’ foxglove is usually in bud by late spring, and the dwarf Chinese astilbe has ferny green leaves that may be tinged with bronze.
Early spring is a good time to tackle the simple cleanup chores: cut down any remaining dead top growth, and clip off any winter-damaged leaves on the perennials that held their foliage through the winter. (If the entire clumps of ‘Biokovo’ geranium look tattered, shear off all the leaves about 2 inches above the ground.) Divide the geranium and the astilbe, too, if they were starting to outgrow their space last year. Both the foxglove and the viola may be short-lived, so if you don’t see new growth on them in early spring, set out new plants in their place. Finish up by spreading a fresh layer of organic mulch over the soil.
Summer: The pageant of pastels peaks in early summer. ‘Etain’ viola, ‘Stairway to Heaven’ creeping Jacob’s ladder, and ‘Biokovo’ hardy geranium are still going from spring, with the addition of ‘Camelot Rose’ foxglove, with its showy spikes of spotted, rich pink flowers. These may all continue into midsummer but are usually finishing up about the time that the dwarf Chinese astilbe sends up its perky lavender-pink plumes.
Regularly removing the flowers when they are finished helps to encourage this extended bloom period. Cut off the bloom spikes of the foxglove and creeping Jacob’s ladder at the base of the plants, and pinch or clip off the individual flowers of the viola. If the viola plants stop blooming in midsummer, cut them back to 3 to 4 inches. Water the garden during summer dry spells.
Fall and Winter: Other than another round of flowers on the ‘Etain’ viola, foliage is the main feature of this garden in fall. ‘Biokovo’ geranium is especially colorful, with its green leaves taking on shades of red, orange, and yellow. The white-and-green leaves of ‘Stairway to Heaven’ creeping Jacob’s ladder often become blushed with pink again now, as well. Most of the perennials in this garden hold their leaves through much or all of the winter. The dwarf Chinese astilbe’s leaves turn brown with frost, but if you left the seed heads in place, they too will add winter interest.
Divide the astilbe and geranium in early fall if they are outgrowing their places, and keep pinching off the dead flowers of the viola. Other than that, your pastel garden doesn’t need any more care until spring.
