Wax Flower Overview

Hoya linearis is a tender evergreen succulent perennial that has a neat cascading habit, with thin long and soft green leaves covered in fine hairs. It produces fragrant, pure white waxy 5-petalled flowers, with lightly tinged pink and yellow coronas. Commonly known as Wax Flower or the Porcelain Flower, it is frequently grown as glasshouse specimens and as houseplants due to their tenderness, but they can be grown outside in sheltered positions and mild climates. If grown under glass, use loam-based compost mixed with equal parts, added bark, charcoal, leaf mould and sharp sand. Prefers placement in bright filtered light. Water freely while in growth and apply a balanced liquid feed once a month. H. linearis's native range is from Nepal to China and is very similar in look to Hoya retusa - the Grass Leafed Hoya, the primary difference being they have slightly different coloured flowers and that H. retusa has a more pom-pom or messy growth habit.
