Answer: Artichokes grow best in the moist, humid, temperate climates of California and Florida, where they are perennial plants. In other regions they are often grown as annuals. If you'd like to try to overwinter them, dig the roots in the fall, brush off the soil, and cut the stems 2" - 3" above the crowns. Then store the roots in a mesh bag in a cool but frost-free place. Replant in the spring.
