Dendrobium christyanum

Dendrobium christyanum is from Thailand, Vietnam and China and has huge flowers for the size of the plant.  My plant is about 5 cm tall and the flowers are about the same size.  It belongs to the group of Dendrobiums known as nigrohirsute Dendrobiums, referring to the black hairs with which the plant is covered and it is sometimes found under the older name, Dendrobium margaritaceum  It blooms in the summer and is temperature tolerant.  The flowers are fragrant.
