Rheum Australe

Himalayan rhubarb is a massive rhizomatous perennial with broad, rounded leaves that may reach 75 cm across, carried on thick reddish stalks. Young foliage can emerge bronze and later develops red autumn tints, while tall summer panicles hold numerous nodding reddish-purple flowers. Native to high mountain country from Pakistan and India through Nepal to China, Rheum australe has long been harvested for its roots, contributing to pressure on some wild populations. In gardens it is best appreciated as a bold ornamental for deep, moist soil and ample space.
