Among the showiest of orchids, Renantheras are mostly bright red, and Ren. coccinea is no exception. Most members of the Renanthera family are quite tall (some up to 10′), which makes Ren. coccinea at 2′-3′, much more manageable. These plants in 3.5″ pots are near blooming size and as a member of the Vanda family, they thrive on lots of sun and humidity.
