Green Spine Rattan
A pretty, slender, clustering climbing palm with pencil-thin stems than can climb to 10 m tall and holds an elongated crown of weakly plumose, pinnate leaves with narrow, grouped leaflets. Calamus viridispinus is native to montane rainforests on the Malay Peninsula and Sumatra between 1000 and 2200 m. It is the source of a rattan cane suitable for tying purposes, basketry and the like. It is apparently not in cultivation yet, but would do well in tropical and warm temperate climates and manage prolonged cool temperatures as well as an occasional light freeze. Together with its clustering habit, this makes it one of the best rattans that can be grown in or out of the tropics.
