Cattleya trianae

Christmas orchid

Colombia's national flower is a unifoliate Cattleya endemic to the Colombian Andes. It is an epiphyte with succulent leaves that grows in premontane and lower montane forest, mostly between about 1,000 and 2,000 m. It is threatened in the wild by habitat loss and over-collection. In cultivation it is an intermediate-temperature Cattleya that needs bright light, a good day–night drop and a drier rest after its winter flowering.

Where it grows wild

Wikipedia describes it as an epiphyte of cloud forest at about 1,500–2,000 m. The GBIF records concentrate on the slopes flanking the upper Magdalena valley in Cundinamarca, Tolima and Huila, with more records in Antioquia, Santander and Caquetá. Most of this is seasonally humid premontane forest and forest remnants in coffee country, where plants grow on the trunks and major branches of trees in well-lit positions. The records hold little habitat detail, and many coordinates are deliberately blurred to protect the species.

Measured records run 440–2,600 m, with a median of 1,483 m (41 records). Wikipedia gives 1,500–2,000 m. The lowest records are probably blurred coordinates or garden plants.
