- Interesting Facts: Epis, as they are called in the horticultural trade, is the largest neotropical genus. Over 150 species make up this mega-genus. The name refers to its epiphytic growth habit. Relatively heavy feeders and need regular fertilizing. Do not let the leaves of an orchid stay wet or the plant can rot. Some epidendrums have pseudobulbs and some have cane-like stems. They cannot survive freezing temps but do well in most temperatures above 50
- Epis like to be pot bound so repot only every 3 years or so. Once you find a spot they love, do not move them. They seem to be sedentary and once chosen a good spot, may cause decline if attempting to relocate.
