Dendrobium senile

White-haired dendrobium

A small Indochinese Dendrobium known as the old man orchid for the white hairs covering its short canes. It grows as an epiphyte in deciduous dipterocarp-oak and evergreen forest from lowlands to about 1700 m, through a hot, wet monsoon summer and a cool, nearly rainless winter, and it is best grown warm and moist in summer with a cool, dry winter rest.

Where it grows wild

An epiphyte on tree trunks and in the crowns of trees such as Dipterocarpus tuberculatus in deciduous dipterocarp-oak forest, in evergreen forest and in open scrub. Labels mention partly shaded trunks and 'rather open deciduous jungle', so it is exposed to strong light, especially when the trees are leafless in the dry season.

GBIF records with an elevation run from 50 to about 1700 m, with a median of about 800 m (Doi Suthep records at 660 and 850 m).
