Wax Flower Overview

Hoya obovata is an evergreen perennial plant from the Apocynaceae family. Originating from Maluku, Sulawesi, Thailand and Vietnam, it is commonly grown indoors as a houseplant. Also known as Wax Flower, this Hoya is considered reasonable fast-growing. This shrubby plant is an epiphyte with arching stems bearing rounded to oval, fleshy leaves. It can be trained on small trellises or pruned to keep it small and neat. The flowers are borne in umbels of star-shaped, white, sweetly scented blooms which are borne in the summer. In summer they should be placed in a sunny position but protected from direct sunlight as they can get scorched. They like to be in a humid environment so regular watering is needed. They can be watered a lot less in winter and left to almost completely dry out but should still be placed in a sunny position or under light.
