Grass Leafed Hoya Overview

Hoya retusa is a tender evergreen succulent perennial with a trailing habit that produces fragrant, creamy-white waxy 5-petalled flowers that have a contrasting red eye - corona. It is commonly called the Grass Leafed Hoya for its slightly flattened, 12cm (5") long and thin green cylindrical leaves that protrude from its stems in every direction and have two almost undistinguished lobes at the end of each leaf. H. retusa 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. Native to West India and East Himalaya, this species is very similar in look to Hoya linearis - the Porcelain Flower, the primary difference being they have slightly different coloured flowers. and that H. linearis has a more cascading habit with leaves that are covered in fine hairs.
