Overview
Hoya Carnosa, the wax plant, is a trailing or climbing evergreen native to East Asia and Australia. It is loved for its thick, succulent-like waxy leaves and its remarkable flowers.
The blooms appear in rounded clusters (umbels) of small, star-shaped, porcelain-textured flowers, usually pale pink with red centers, and release a sweet fragrance, often strongest in the evening, along with droplets of sticky nectar.
It is a hardy, long-lived plant that tolerates some neglect. Flowers form on persistent stubs called spurs, which should never be removed, as they rebloom year after year.
How to identify it
Recognize it by:
- Thick, glossy, waxy oval leaves, sometimes splashed with silver flecks or variegation
- A trailing or twining vine habit, often grown in hanging baskets or on trellises
- Umbels of star-shaped flowers, typically pale pink with a red or darker central star, with a porcelain or waxy sheen
- A sweet, often evening fragrance and sticky nectar droplets
- Persistent flowering spurs from which new blooms emerge
Care & growing
Famously low-maintenance.
- Light: Bright indirect light encourages blooming; some morning sun is fine
- Water: Let the soil dry out between waterings; the succulent leaves store water and it dislikes constant moisture
- Soil: Well-draining, airy mix; many growers use an orchid-style bark blend
- Temperature: Warm, 18 to 27 C (65 to 80 F); tolerates average humidity
- Feeding: Light balanced or bloom fertilizer in the growing season
- Propagation: Very easy from stem cuttings with a node, rooted in water or mix
- Tip: Do not remove the flower spurs; new flowers rebloom from them. Slight rootbound conditions encourage flowering
Habitat & origin
Native to East Asia and Australia, including southern China, India, and parts of Southeast Asia and eastern Australia.
It grows naturally as an epiphytic climber in tropical and subtropical forests, scrambling over trees and rocks. Worldwide it is a popular, durable houseplant and is grown outdoors in frost-free climates.
Frequently asked questions
Why won't my Hoya Carnosa bloom?
It needs sufficient bright light and maturity to flower, and it often blooms better when slightly rootbound. Be patient and never cut off the flower spurs.
Should I cut off the old flower stalks?
No. Hoyas rebloom from the same persistent spurs each year, so removing them prevents future flowers from forming there.
How often should I water it?
Let the soil dry out between waterings. The thick, waxy leaves store water, so it is prone to rot if kept constantly wet.
