Hoya pubicalyx 'Royal Hawaiian Purple'
Purchased top cutting from Jackie June 28, 2026
Hoya pubicalyx 'Royal Hawaiian Purple' is a fast-growing woody epiphyte or scrambling shrub with pretty neat flowers. The flowers are up to 0.4 inches across and come in bunches of 20 to 40 hanging from along the stems. The bunches are up to 4 inches across. You can see clusters with pink-red flowers, and also, on the same plant, you might see almost black clusters. Some of the clusters are even mixed pink and black. The narrow, up to 4 inches (10 cm) long leaves show some silvery-grey flecking patterns.
How to Grow and Care - Hoya plants don't ask for much beyond the well-draining soil and the warm, humid conditions that many tropical flowers crave. They don't like wet feet or heavy soil, and as many grow as epiphytes in nature (similar to bromeliads and orchids). Give them at least a half-day of sunshine and bring them indoors when temperatures drop below 50 degrees F.
When your Hoyas finishes blooming, leave the flower stalk, as it may produce new flowers. Removing the stalk forces the plant to produce a new stalk, which delays blooming and wastes the plant's energy. They are light feeders, and a monthly drink of compost tea or dilute fish emulsion provides all the nutrition these tropicals need. Hoyas like the security of a snug pot and plants that are a bit root bound will flower more prolifically than those swimming around in a giant pot.
