Cynara scolymus
HEIRLOOM. The classic, most popular artichoke variety. Beautiful plants grow up to 6 feet tall with arching silver-green foliage. The large, edible flower buds grow to 3 to 5 inches in diameter, are deep green with purple-tinged edges, and have thick, fleshy scales and tender, flavorful hearts. A must-have for Mediterranean cooking.
Green Globe artichokes can be grown as a perennial in zone 7 and higher, or as an annual as far north as zone 3. They need full sun and rich, well-drained soil. Start seeds indoors 8-10 weeks before last frost, and transplant out after the risk of frost has passed. Plants need exposure to cool temperatures below 50 degrees F for around 10 days to trigger flowering, but will not tolerate frost. Expect production of artichokes about 120 days after seeding. 1 gram packet contains a minimum of 20 seeds.
