Known as the wax flower, Hoya is a genus of plants native to Asia, Australia and the Pacific islands. Hoya carnosa bears clusters of night-scented, star-shaped, white flowers in contrast with fleshy dark green leaves up to 8cm long. The wax flower needs a minimum temperature of 10°C to thrive.
For best results, grow Hoya carnosa in containers of compost with added bark, and spray with water regularly to increase humidity. Water freely and feed monthly when in growth. Reduce watering in winter but keep the compost moist.
