Peacock orchids are a small group of beautiful, mainly terrestrial, but at times epiphytic or lithophytic miniature orchids. This genus of orchids was named after Pleione, the mother of the Pleiades in Greek mythology and it comprises of about 20 species. Peacock orchids are distributed in the mountains and foothills of the Himalayas, India, Myanmar, Thailand, Laos, Vietnam and China. They can adapt well to cold temperatures and even frost but a few prefer a warm climate. They grow in well-drained habitats and on rocks covered with moss at an altitude between 600 to 4200 meters.

Peacock orchids have a large, spongy, globular or ampliform pseudo-bulbs that are narrowed at the apex. A pseudo-bulb is active only for one year and they drop off before winter. The pseudo-bulb remains dormant till a new one starts to develop. The flowers originate from the top of the pseudo-bulb.

Peacock orchids can easily be grown by a layman, being easy to propagate which makes them among the most popular orchids. They are quite in demand for hybridization.
