This variety has curious curled leaves. Very slow growing and showy. Hoyas are adaptable plants found everywhere from true rain forests through the slopes of the Himalayas, from semi-arid niches in Australia to damp forests. They range from vines, the most common form, to shrub-like growth. Most are epiphytic. Hoyas are in the family commonly known as milkweeds. They are most closely related to Stapelia, Ceropegia and Dischidia. They were first identified as a new genus by Robert Brown in 1802. There are now several hundred distinct species. Many of these species are in cultivation. Var. Crispa Variegata has variegated leaves.
