Hoya macgillivrayi is a fast-growing succulent climber with thick, oval, pointed leaves which are light green and set opposite each other on the twining stems. The flowers are up to 2.4 inches (6 cm) wide on long stalks and are borne in umbels of 6 to 10 flowers that are each connected at a central axis. Each flower is a dark burgundy color with five sepals and five petals. The stamen are enclosed in the corona. The fruit produced are two pairs of follicles that are 10 inches (25 cm) long from which a flat seed is produced that is distributed by the wind.

How to Grow and Care

Hoyas 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. Give them at least a half day of sunshine, and bring them indoors when temperatures drop below 50 °F (10 °C).

Hoya 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 that are swimming around in a giant pot.

Propagate Hoyas by cuttings of top growth or by leaf cuttings. The average cutting or leaf start will produce a blooming plant in 2 years or less. The easiest method of propagation is by layering… – See more at: How to Grow and Care for Hoya
