When I started to grow orchids this plant was a color form of Epi. purpuratum. But through the years the taxonomists keep changing the name. The color form of my plant is 'randii' and the genus just keeps changing every few years, so I use the original name. This orchid grows in a pot that hangs in a mango tree. Every so often I fertilizer it, but most of the time it's on it's own.
