A short-lived perennial reaching a height of 60cm. Frost hardy. It prefers moist, warm climates but grows in cooler regions and tolerates some dryness. Prefers a sun or semi-shade position in well-composted soil. Use the fresh young leaves, which have a lemony flavour, in salads, soups or with fish. The leaves do contain oxalic acid which is fine in small amounts, but avoid if you have a history of kidney stones.
