Rumex

These hardy perennials grow mainly as pesky weeds. The leaves are usually lance-shaped and vary in length from a few inches to a few feet. Some have bright green leaves, some are stained or striped with red, and one, R. sanguineus, has blood red veins. R. Hydrolapathum, the Great Water Dock, grows up to 7 feet high. The length of its leaves average 2 feet. It is sometimes planted in shallow water on the edges of ponds for the beauty of its large leaves. R. acetosa, the Garden Sorrel, is a frost-hardy perennial that is used as a vegetable. The Garden Sorrel is an upright, leafy plant that forms thick bunches, 12 to 18 inches high and up to 3 feet when in bloom. The smooth leaves are lance- or arrowhead-shaped.

Pot Cultivation

These plants grow in full sun in regular garden soil. They should be planted a foot apart. If the soil is properly drained, the Garden Sorrel will live for many years. It can be cut to the ground once or twice during the growing season. Feed and water to encourage new growth. Feedings of manure tea is very beneficial. The seed stalks should be snapped off as soon as they pop up. The leaves of the Garden Sorrel may be snapped or cut off at any time. Sorrel has an acidic, lemony taste and is used as a potherb, in leek soup, salads, or to line the dish for baking fish. The young leaves are very tender, therefore they cook quickly. Older leaves, however, are very tart and may need two or three changes of water to reduce tartness.

Propagation

Sow seeds outside in the spring or fall.
