Dendrobium ruckeri

Rucker's dendrobium

A cool-growing epiphytic Dendrobium of the eastern Himalaya and the Khasi and Jaintia Hills, with slender, branching stems that become pendulous with age. It carries fragrant flowers of about 3.5–4 cm, one or two together near the stem tips, in late winter and spring. Its home has a hot, very wet monsoon summer and a cool, drier winter, and the plant does best with that cycle.
