Globe Artichoke
Green Globe Improved Artichoke is a cultivar of Cynara scolymus bred to deliver reliable harvests of tender, deeply flavorful buds in 150 to 180 days. This is the artichoke many American gardeners reach for, a trusted performer across USDA zones 7 through 10 that thrives in full sun and rewards careful timing with handsome globe-shaped heads ready for steaming, roasting, or preserving. Whether you're in a mild climate where it grows as a perennial or a colder region where you'll start seeds indoors, this variety has been refined to germinate reliably and establish quickly once transplanted.

Green Globe Improved lives up to its name through consistent, generous production of tight, globe-shaped buds that are tender enough to eat whole when young. The variety responds well to indoor seed starting, germinating reliably at 70 to 80 degrees Fahrenheit and ready to transplant within weeks. In mild climates, you can sow in early fall for a spring harvest, while cold-climate gardeners can start seeds indoors 12 weeks before their last spring frost and see mature plants producing within a single season.
Artichoke buds are steamed whole and eaten with melted butter or aioli, with diners plucking tender leaves and scraping the flesh between their teeth before reaching the prized heart. The buds can be roasted with olive oil and garlic until the outer leaves crisp and char, quartered for salads when very young and tender, or preserved through pickling and canning. Green Globe Improved's reliable size and consistent maturity make it equally suited to fresh market growers and home cooks looking for an impressive yet achievable harvest.
In cold climates, sow seeds indoors in 4-inch biodegradable pots 12 weeks before your average last spring frost date. Maintain soil temperature at 70 to 80 degrees Fahrenheit for reliable germination. Transplant outdoors four weeks before your last frost date, hardening off seedlings gradually to outdoor light and temperature. In mild climates, sow in 4-inch biodegradable pots in early fall instead, allowing seedlings to establish during cooler months.
Transplant outdoor-hardened seedlings four weeks before your last spring frost in cold climates, or six weeks before your first fall frost in mild climates. Ensure soil temperature is at least 60 degrees Fahrenheit. Space plants six inches apart in rows six inches apart. Protect young transplants from unexpected frost in cold regions.
Direct sowing is not recommended in cold climates. In mild climates, you may sow directly in fall for spring harvest, though indoor starting is generally more reliable.
Harvest buds when they reach full size but before the bracts begin to open and separate. Cut the central bud first with a sharp knife, removing about one inch of stem below the base. Once you harvest the main head, secondary smaller buds will form along the stem and can be picked as they mature. Continue harvesting over several weeks to encourage more production.
