Grow artichokes anywhere, even in northern gardens. 'Green Globe Improved' is a short-season variety and 'Purple of Romagna' is a coveted, Italian heirloom. Provide plenty of room and fertile soil and you'll be rewarded with 3 to 5 fresh, delicious artichokes per plant. Bees love the flowers! Perennial in USDA zones 7-10 or bring indoors over winter. In cold climates, can be grown as an annual.
