GROWING INFORMATION SCIENTIFIC NAME: Cynara scolymus
CULTURE: Artichokes and cardoon require very fertile, well-drained soils with a pH of 6.5-7.0. Sow artichokes indoors 8-12 weeks before last spring frost date. Cardoon is more vigorous and can be started later, 6-8 weeks prior to last frost date. Plant 2-3 seeds per cell in plug trays or individual containers 1/4" deep. Germinate at 70-80°F (21-26°C). As soon as seedlings can be handled, transplant to 4" pots or 11⁄2" cell-type containers and grow at 60-70°F (15-21°C) day and 50-60°F (10- 15°C) night. Transplant 6- to 12-week-old plants to the field 2-3' apart in rows 4-6' apart.
GLOBE ARTICHOKES:

HARVEST: Clip mature buds midsummer to midfall, depending on location.
MILD AREAS: Where winter low is above 14°F (-10°C), sow seeds in fall, harvest in spring. SEED SPECS: SEEDS/LB.: Avg. 11,500.
