Cynara cardunculus var. scolymus 'Green Globe'
vegetableThe Green Globe artichoke is grown for its large, rounded, immature flower buds, eaten for their tender leaf bases and meaty heart before the bud opens into a purple thistle flower. A tender perennial that lives for years in mild-winter regions on five-foot, silvery plants, it is grown as an annual in cold climates by tricking young plants into budding their first year.

In mild regions grow artichokes as a perennial in full sun and rich, deep, well-drained soil with plenty of water and feeding. Where winters are cold, start seed indoors in winter and vernalize the seedlings by exposing them to about 45 to 50F for ten to fourteen days before transplanting, which convinces the plants they have overwintered and prompts them to form buds the first season.

Good neighbors that attract beneficial insects or deter pests
Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide
Hose off colonies and encourage ladybugs and lacewings with flowers
Remove and destroy old stalks and infested buds; keep the planting clean
Trap and hand-pick after dark; keep mulch from staying soggy
Cut the buds while they are still tight, firm, and plump, with an inch or two of stem, starting with the large terminal bud and then the smaller side buds that follow. Harvest before the bracts begin to loosen or open, since once the bud starts to flower it turns tough and inedible.
Artichokes are high in fiber and a good source of folate, vitamin C, vitamin K, and magnesium, and they are especially rich in antioxidants and in inulin, a prebiotic fiber that supports gut health.
