belongs to the Centrostemma group of Hoyas. Unofficiall...Read Morey some place this species under the Genus of Centrostemma and not Hoya due to it's more or less shrubby growth and differing flowers.
Native to: China, Indonesia, Laos, Malaysia, Myanmar, Philippines, Thailand, Vietnam.
Upright growth, often branching creating a shrubby look. Trim top if not branching. It is said that in the wild it has been seen growing vine like up trees.
Leaves are very thin and wavy around the edges.
Exudes thick milky white sap when cut or broken.
In general very easy to grow and flowers early on but is prone to "bud blast" if it dislikes growing conditions. May flower several times from same flower stem but also may throw it after the first blooms faded.
Use well draining soil and keep consistently moist (can keep pot in saucer of water), likes it warm and humid and doesn't tolerate cold drafts too well.
There are also variegated and spotted leaf forms available in the trade.

I keep mine out of drafts from the ac/heat vents otherwise I have noticed it will blast the buds. When ever I've let the plant dry out it drops its buds and has on occasion gotten brown tips on the leaves. They both are constant bloomers and I have not noticed any fragrance in the blooms.

Hoya multiflora’s native range is from the Philippines to Indonesia and west to Peninsular Malaysia. It has been given many common name...Read Mores, the most used being 'Shooting Star’ Hoya. It is very different from other species of Hoya for its bushy upright habit. A shrubby plant with thin, succulent leaves and clusters of yellow and white waxy flowers resemble shooting stars. A great Hoya for those with small areas. Some H multiflora have silver flecked leaves. Give this plant bright filtered light and a minimum temperature of 60 degrees. Let dry between waterings.
