Dendrobium Gina Perlite 'Crystal White'

This beautiful hybrid of the tiny Dendrobium cuthbertsonii and the hard-to-grow Dendrobium prasinum is seldom out of bloom and is much easier to grow and more warmth tolerant than either of the parents.  It is a slightly larger plant than Dendrobium cuthbertsonii and the leaves have only a hint of the "pebbled" surface of the leaves of that species.  Why this plant's clonal name is 'Crystal White' I do not know since the flowers are a soft yellow color.
