Yes, They can be grown in most of the US.
Treat artichokes as annuals in cold climates. In milder regions, cut the plants back in mid to late fall. In
zones 8 through 10, they should need no winter protection. In
zones 4 through 7, cover each plant with an inverted bushel basket and mound pine needles or leaves on top.
Buy them at your local nursery or start
seeds 8-12 weeks before your last frost date.
