Artichokes are in at Four Season Farm! Beautiful Imperial Star artichokes grown as annuals in Maine. If started in February, vernalized for 6 weeks in the spring, and then transplanted outdoors in late May, they can be ready to harvest by late July. Typically one primary head about 4" in diameter, plus 5-7 slightly smaller secondary buds, per plant. Because they are grown as annuals, there is very little fuzzy choke so you can eat the whole heart - absolutely delicious! Eliot is fond of saying that he likes to grow artichokes in Maine just to make the Californians nervous.
