Dendrobium cuthbertsonii bicolor

This is one of a number of bicolor Dendrobium cuthbertsonii I own, and this is one of the better examples, with very large and very open flowers.  Like other examples of this species the plant itself is tiny, only 2 cm tall, with 4 cm flowers.  Some of the plants of this species I grow mounted.  This is grown in a clay pot in live sphagnum, but does no better than those that are mounted.
