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.
