Care: Regular watering is best. Carrots will go dormant and may even lose their leaves during excessive droughts or hot weather, but they sprout back when conditions get better. The roots from such carrots are woody and tasteless, but the carrots will still flower and produce seed.
Carrots are quite cold hardy, withstanding temperatures into the low teens (°F), and even seedlings can tolerate moderate frosts. Flavor is enhanced by frost. Mature carrots can be left in the ground over winter. Protect with mulch during severe freezes.
Carrot roots are high in carotene which humans convert to vitamin A. The black swallowtail butterfly lays its eggs on plants in the carrot family, and the caterpillars feed on the foliage, so grow a few extra carrots for the butterflies!
The root of the wild carrot, or Queen Anne's lace, is also eaten, and its aromatic seeds are used as a flavoring.
Carrot is a caterpillar host plant for Anise Swallowtail and the Eastern Black Swallowtail
