Rhubarb

Rhubarb Overview

Rheum rhabarbarum is a hardy, herbaceous perennial that grows from rhizomes, from the Polygonaceae family. Commonly known by the names Rhubarb or Garden Rhubarb, amongst others. Rhubarb is an easy to grow, very low maintenance plant, but will produce better crops if given a little care. The bright stems are a colourful addition to any vegetable patch and they can produce a crop for many years. Grow in full sun for the best results, it can also cope with some light shade and typically exceeds 1m in height and spread. Well-draining, moist soil is best and provide plenty of space for Rhubarb to grow. It may struggle on particularly alkaline or acid soils, a neutral pH is best. Originating from Siberia to China, this plant has a long history of cultivation, with both medicinal and culinary uses. Many cultivars now grown for the bright, edible stems have been developed from hybridisation with this wild ancestor. The edible stems may be consumed raw or cooked, often in sweet dishes. The leaves are large, roughly textured, broadly triangular and inedible due to high levels of oxalic acid and anthrone glycosides. Flowers are cream-green pinkish in colour, produced above the foliage in panicle arrangements. If growing for the stems, its best to remove the flowers as they start to form as flowers take energy from other growth, decreasing the potential leaf and stem production.
