J. Linden and Rchb.f 1860
This beautiful plant is the national flower of Colombia and could be the most cultivated Cattleya species. Variable, with large flowers that range from purple to white with a deep purple lip and a yellow throat. Cattleya trianaei is widely distributed throughout the mountains of Colombia, where it grows epiphytically. In the northern hemisphere it is a mid winter (late December to February) bloomer. In Colombia , Cattleya trianaei is commonly known as the Flor de Mayo (May Flower), yet it often blooms around Christmastime as well as late spring. Originally published, in 1860, as Cattleya trianaeto honor Dr. Triana, a Colombian botanist. Incorrectly adding an "e" to Dr. Triana's name technically changed him into a woman. The incorrect feminine name ending persisted until 1970, when the RHS corrected it to trianaei by adding an "i". Typical Cattleya culture , with ample light and fertilizer suits this species well.
