Rheum nobile
Also called Noble Rhubarb
Rheum nobile, the Sikkim rhubarb or noble rhubarb (पदमचाल), is a giant herbaceous plant of the Buckwheat Family (Polygonaceae) and native to the Himalayas, from northeastern Afghanistan, east through northern Pakistan and India (in Sikkim), Nepal, Bhutan, and Tibet to Myanmar, occurring in the alpine zone at 4000–4800 m altitude.
It is an extraordinary species of rhubarb (genus Rheum). At 1–2 m tall, the monocarpic inflorescences of R. nobile tower above the other shrubs and low herbs in its habitat, and it is visible across valleys from several kilometres.
