Rheum rhabarbarum

Description

A large herbaceous perennial which overwinters as a short crown, and in spring produces triangular to heart-shaped dark green leaves with strongly wavy edges, held on thick, angular, hollow reddish stems. In mid summer, dense panicles of small yellow-white or greenish-white flowers are held on upright stems above the foliage, followed by flat, tan-coloured seeds. This species may have been involved in the parentage of the hybrids now used as culinary rhubarb
