Hoya is a plant genus of about 200–300 species. Most have waxy, slightly thick leaves. It’s a keen climber that can wind a long way with the right support from steel or plant wire. The waxplant is known for having fairly modest requirements. Given ideal growing conditions, it will form attractive, porcelain-like flowers which have a strong scent, particularly in the evening.
LIGHT
A waxplant should ideally get 12 hours of continuous light. It does fine in direct sunlight, but it doesn’t like draughts and grows best at temperatures over 15°C (59°F).
WATERING
It must be allowed to dry out between waterings. During spring and summer, it likes to be watered a few times a week, but much less frequently during autumn and winter.
SOIL
Use ordinary potting compost with a layer of leca balls in the bottom. You can also mix a few leca balls into the compost to ensure good drainage.
FEEDING
Feed with liquid organic plant food once a month from spring to autumn.
ORIGIN
The waxplant orginates from forests in Australia and Asia.
MISCELLANEOUS
To stimulate flowering, make sure you stand your waxplant in direct sunlight. The waxy flowers produce large drops of nectar – so watch out for sticky drips on your favourite table top! Note that the sap inside the leaves can be a skin irritant.
