Biology

Red sorrel has a creeping root system and spreads aggressively by underground roots and rhizomes. The upright, somewhat woody stems grow to a height of 1/2 to two feet, with little branching in the lower portions. Leaves are alternate on the hairless stems, with short petioles and a papery sheath at the point of attachment to the stem. The leaves have a distinctive lance or arrowhead shape, with two narrow lobes at the base of the blade. Reddish flowers are borne in loose clusters on branching stems at the top of the plant. Red sorrel is dioecious, bearing red-brown female flowers and yellow-green to red-orange male flowers on separate plants. The glossy, reddish-brown seeds are triangular in shape and are typically enclosed by the persisting remains of the flowers.

Habitat

Red sorrel thrives on acid soils, but it is well-adapted to many soil types and growing conditions. It may be a weed of waste places, lawns, fields, gardens, and roadsides.
