Heirloom Vegetable

First year artichokes are small & few in number but can still be suitable for harvest. Higher quality artichokes develop in the second and third years – therein lies the gardener’s greatest challenge. Artichokes will not survive winter in most areas of Canada! We suggest digging up and overwintering dormant roots in a cool area indoors if you do want to try for a second year harvest.

 

"Green Globe" has deep green buds with a slight purple tinge.

The artichoke flowers are best harvested when 5-9 cm (2.5-4") in diameter.

The fleshy base of the flower scales and the firm centre are the edible portions.

Plants can reach 1.5m (4.5’) in height in one year.

Artichoke is a tender perennial hardy from zone 7 up.

20 seeds/gram Start seed indoors in a soil-less mix 8-12 weeks before the last frost date in your area. Sow the seed 6mm (1/4") deep and germinate at 21-26 C (70-80 F). When seedlings are 2.5-5 cm (1-2") high transplant to individual 10 cm (4") pots and grow on at 15-21 C. Harden off and transplant to the garden after the threat of frost has passed. Artichoke does best in full sun with a deep, organic, fertile soil.

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.
