Hoya polyneura

Fishtail hoya

The fishtail hoya is an epiphytic climber from the eastern Himalaya, named for its rhomboid, fishtail-shaped leaves with many fine parallel veins; it bears clusters of white flowers with red-purple coronas in late summer. It grows in broad-leaved evergreen forest at about 900–2000 m, so it prefers intermediate to cool temperatures, bright shade, humid summers and a cooler, drier winter.
