Hoya retusa (narrow leaves)

N. A. Dalzell

Published in Hooker's Journal of Botany and Kew Gardens Miscellany 4 294 (1852) by N. A. Dalzell. Hoya retusa originates from India. It was found by N. A. Dalzell in Canara (coast province of the state Karnataka), India. The name retusa refers to the leaf shape and means rounded, shallowly notched end.

Hoya retusa is an odd looking plant. The leaves are 5-6 cm long, but only 2 mm wide. They grow in large clusters in each node so the plant makes a fuzzy impression. It needs much light and cooler night temperatures promotes flowering. Although Hoya retusa has

some climbing ability I think it's best grown in a hanging basket. I recommend at least 4-5 cuttings in the basket to make a nice looking plant.

The flowers only come one or two in each cluster. This is often compensated by many clusters flowering at the same time. The flowers are flat and they are white with wine-red coronas. The scent is weak and reminds of lemon. Hoya retusa flowers mainly in autumn, from October 'til November, but can also flower other times of the year.
