Hoya uniflora

Unrooted cutting of Hoya uniflora.
Three to five nodes.

Hoya uniflora is a tiny, unusual Hoya species native to Laos, known for its miniature foliage and remarkably large solitary white flowers.

The leaves are very small, thick, and fleshy, generally ranging from oval to nearly round. Mature leaves may develop a subtle central fold and a glossy surface. One of the most distinctive characteristics described in the original species publication is the underside of the leaf, which can appear very pale to almost white with a greener or silvery-green band running along the midrib.

Despite the miniature foliage, the flowers are surprisingly large. Hoya uniflora produces one flower at a time rather than the multi-flowered umbels typical of most Hoyas. The flowers are pure white, approximately 3 cm across, softly hairy on the inner surface, and reported to have a sweet fragrance.

Hoya uniflora was formally described in 2017 by Leonid Averyanov and Van The Pham from material collected in Xiangkhouang Province, northeastern Laos.

The original population was found growing primarily as a tiny creeping lithophyte on moss-covered limestone rocks and cliffs at approximately 1,200–1,450 meters elevation, with some plants also growing epiphytically. Mature vines in the original description reached only about 35 cm long.
