Culture
Winter hardy in Zones 10-12. Typically grown as a houseplant. Best grown in standard, well-draining, loamy potting mix with bright, indirect light and some direct light. Water plants moderately but consistently throughout the growing season, allowing the soils to become nearly dry between water applications. In winter, plants require less bright light, less watering, and tolerate cooler temperatures. Do not move or reposition plants once buds are set.
Noteworthy Characteristics
Hoya nummularioides is an epiphytic, twinning, evergreen vine native to mainland Southeast Asia. The leaves are small, fuzzy, leathery, and rounded to slightly ovate in shape, reaching around 1" long and 0.75" wide. Tight, rounded umbels, of small, fragrant, white and pink, five-lobed flowers bloom seasonally, once or twice a year depending on the climate.
Genus name honors Thomas Hoy, late 18th century gardener to the Duke of Northumberland.
The specific epithet nummularioides means "coin-shaped" or "coin-like" in reference to the small, rounded leaves of this species.
Problems
Overwatering may cause root rot. Watch for mealy bugs and scale.
Uses
Trailing houseplant for hanging basket, or trained up a trellis.
