Ornithoboea arachnoidea was introduced into cultivation only in the early 1990s, but since has been quite widely distributed. It is notable for the covering of most plant parts, aside from the flowers, with arachnoid hairs (spider web- or felt-like). These are often most abundant on flower stems and the backs of the calyces, resulting in a woolly effect in flower clusters. The tiny lavender flowers have a distinctly orchid-like appearance.
Growers report that the plant prefers high humidity and low light, and in these conditions the leaves are covered in fine white hairs. With lower humidity the hairs on the leaves are less prominent.
