The Green Globe artichoke is a perennial heirloom variety with silvery-green leaves. Hardy in USDA zones 8 to 11, plants require a long growing season. Green Globe artichoke plants grow to height of 4 feet (1 m.). The flower bud, the edible part of the artichoke plant, develops on a tall stem from the center of the plant. Green Globe artichoke plants produce three to four buds, which are 2 to 5 inches (5-13 cm.) in diameter. Keep the soil moist but not soggy
In hardiness zones 7 and colder, Green Globe artichoke plants can be grown as annuals. It’s best to transplant artichoke seedlings into the garden after danger of frost, but don’t hold off too long. To ensure blossoming the first year, artichokes need exposure to temperatures below 50 degrees F. (10 C.) for a minimum of ten days to two weeks. If an unexpected late frost is in the forecast, be sure to use frost blankets or row covers to protect artichoke plants.
