White Dendrobium Orchid. There are more than 1,000 Dendrobium species that are native to Southeast Asia, including the Philippines. They can also be found in India and Sri Lanka eastwards to Japan and Korea and south to Australia, New Zealand and Fiji. These orchids are one of the easiest to grow. The genus Dendrobium was established by Olaf Swartz in 1799. The name Dendrobium comes from the two Greek words dendron (meaning tree) and bios (meaning life) and probably refers to their epiphytic habit.
