'Green Globe Improved' - (Non-GMO) Artichoke (Heirloom)
Green buds with a slight bit of purple. Best harvested when 5-9 cm (2.5-4 inches) in diameter. Plants reach 1.5m (4.5') high. Best grown in containers or greenhouses to allow plants to survive the winter in Canada. The plants can also be dug up when dormant and relocated to an indoor location for the winter. Even though an artichoke plant can give an harvest on the first year, it is actually the second and third year where these produce the best.
Space plants 60-90 cm (24-36") apart in the row with rows 1.75 m (6') apart. Keep plants evenly watered and mulch the soil to help preserve soil moisture and keep the soil from becoming too warm in summer - if the soil does become too warm, it can trigger a summer dormant period. Start with a thin layer of mulch and build it up to 10 cm (4") thick as the plants grow.
