With crumpled, frilled edges, the bright green leaves impart a mild, mustardy flavor. Served raw, the young leaves are tasty in salads-they're also delicious lightly stir-fried or sauteed. Superb candidate for freezing or canning. Cold-resistant and slow to bolt, the large, upright and vigorous plants spread to 18-24". Harvest young leaves in about 50 days or more mature leaves in about 70.
