Parsley—curly or flat-leafed—is an easy-growing, nutrient-packed herb, planted as both annual and biennial depending on climate. The two main types, P. crispum var. neapolitanum (Italian) or P. crispum var. crispum (curly), are rich in vitamins A, C, and K, and folate, and they also contain phytonutrients. Parsley plants are also home to caterpillars that become the black swallowtail butterfly, so try planting enough for everyone. Parsley is ready to be harvested when stems have three segments. For fresh parsley through winter, repot an outdoor plant and place by a sunny window.
