Disa stairsii, the Rwenzori mountain orchid, is a terrestrial orchid from high-altitude heath and moss zones of the Rwenzori Mountains and Congo. It is a cool-climate species best left to specialist growers, as it needs cool, moist, airy conditions rather than ordinary houseplant care.

About

Disa stairsii (Rwenzori mountain orchid) is a species of Disa of the family Orchidaceae that can be found growing with the giant heathers on the Rwenzori Mountains of mountains in East Tropical Africa as well as in the Congo in West-Central Tropical Africa. It was first collected by Lieutenant Stairs in 1889, during the Emin Pasha Relief Expedition, whilst he was carrying out the first European exploration of the Rwenzori Mountains.

Disa stairsii is cardinal red, distinct from the other foliage by its single spur which is borne on the top of its flower and is generally growing in moss between the altitudes of 2,800–3,400 meters (9,200–11,200 feet). It is common in the heath belt of the Ruwenzori Range. On Kilimanjaro D.
