The plant is one of the largest of the genus Lepanthes. Its growths are around 45 cm tall and the individual leaves about 8 cm long. the name orion refers to a mythical giant, but the reference is not to the size of the plant but of the flowers, which are quite large for a Lepanthes, about 2 cm, though rather small in relation to the leaves. The flowers are very intricate and colorful.
Each leaf continues to produces flower spikes and flowers over a very long period of time, so that the plant is almost always in bloom. It is native to Ecuador and Colombia and requires cool and moist conditions not unlike its native habitat. Given these it is easy to grow and flower.
