Dendrobium cuthbertsonii bicolor

This is one of my many plants of this charming species.  It comes in a rainbow of colors including this bicolor form, and has flowers that last for months.  Dendrobium cuthbertsonii is from the highlands of New Guinea, is a micro-miniature plant, 2 cm or smaller with huge flowers.  It is cool growing and does not thrive unless the temperatures are kept down, but very high light will compensate to some extent for higher temperatures.  I grow some plants mounted and some in pots in live sphagnum and all do well for me.  This plant is a bicolor and has unusually large flowers.  It is probably a polyploid.
