Sorrel begins growth in early spring, providing salad greens when few other edibles are available. The plant thrives in full sun or partial shade, and it prefers moist soil. Some types can be grown in shallow water. Sorrel develops a mound of foliage that grows 12-18 inches tall, and it sends up a flower stalk with green flowers that mature to reddish-brown seeds. Remove seed stalks to prevent the plant from self-sowing.
