While Italian parsley is frequently the parsley of choice due to its more robust flavor, curly parsley does have a place in the cook's garden. The curly dark green leaves are as attractive in the garden as they are as a garnish. Its muted flavor may be appropriate in egg salad or chicken salad sandwiches, and parsley is a good source of vitamins A, K, and C. That said, curly parsley is an easy-to-grow summer green, given lots of sun and well-draining soil. Perfect in pots, curly parsley can be harvested as needed, but leave at least a third of the plant so it can regrow. As a biennial, parsley has the best flavor in its first year of growth, so we treat it as an annual.
