Summary
Sorrel is a leafy green vegetable grown for its pleasantly tart, lemony flavor. It sometimes gets classified as an herb and sometimes as a vegetable.
Description
Sorrel plants have smooth, arrow-shaped leaves that grow from a center rosette. The plant will send up a tall flower stalk as the temperature warms, but it's best to remove this to promote leaf growth for a better harvest. The red flowers are rather insignificant whorled spikes, like rhubarb.
Additional Info
Sorrel only gets about 12 to 18 inches tall, although the flower stalks (if left on the plant) will get taller. It does spread out though, easily taking up 2 feet in width. Sorrel is typically planted in spring and has a moderate growth rate; young leaves are ready to harvest in a little over a month.
