Hoya Retusa, Wax Plant, Grass Leafed Hoya: This plant drapes beautifully, with very long and slender foliage that looks grasslike and graceful. Each blade is actually an extremely thin paddle shape. The foliage can be trained to trail along structures such as curtain rods and shelves, or it can cascade over a plant pot. While other Hoyas have clusters of waxy, porcelain-like flowers, this plant shows them off individually... small and creamy white, with just a touch of maroon in the centers, falling here and there amid the flurry of foliage. Flowers have a faintly citrus scent, adding to the ethereal quality of this plant.
