Dendrobium cuthbertsonii is a plant I've posted many times. The flowers come in a rainbow of colors and I have many different plants of this choice species. This is one of my favorites with huge and beautiful bi-colored flowers. It is also a smaller plant as this species goes. None of them are large but some form a creeping mat while others have tiny upright growths. This is more the creeping type. The species is from New Guinea and requires cool temperatures and high humidity.
