The Story
Plant Bio
Hoya carnosa, wax plant, is an epiphytic climbing vine from Southeast Asia, Japan and Taiwan, trailing or twining several feet. Thick leathery leaves with a waxy surface line the wiry stems, and rounded clusters of small star-shaped flowers in white and pink open in summer, each with a darker central crown and a strong evening scent.
Never cut off the stubby leafless stalks the flowers grow from — those are the spurs, and the plant reblooms from the same ones year after year, so removing them costs you future flowers. It also flowers best slightly pot-bound and a little neglected, which means the usual instincts to repot and feed generously both work against it.

Planting
How to Grow
- Give it bright indirect light, with a little direct sun.
- Use a very free-draining, bark-based compost.
- Let it dry out substantially between waterings.
- Leave it pot-bound; repot only every few years.
- Never remove the old flower spurs.
- Support the stems on a hoop or let them trail.
Pro Tip
The stubby stalks left after flowering are the spurs it reblooms from — cutting them off is the commonest reason a hoya never flowers again.
