How to Grow Green Globe Artichokes from Seed

Start artichoke seeds indoors 8–12 weeks before your last spring frost date. To encourage heavy first-year bud production in Canadian climates, sow seeds 6–13 mm (1/4 to 1/2 inch) deep in rich, sterile seed-starting mix and maintain warm germination temperatures around 21–24°C (70–75°F).

Once seedlings have 3–4 true leaves, subject them to a cool period (vernalization) by exposing plants to steady temperatures around 10°C (50°F) for 2–3 weeks before final outdoor planting. This deceives the plant into thinking it has passed winter, triggering abundant flower buds in its very first season.

Harden off seedlings carefully and transplant outdoors after frost danger has passed into fertile, well-draining soil rich in organic matter. Space plants 60–90 cm (24–36 inches) apart in rows.

Water deeply and consistently throughout the summer. Harvest tight, firm flower buds in late summer before the lower scales begin to open or flower.

Growing Artichokes in Canada

While historically grown as perennials in warmer Mediterranean climates, Green Globe artichokes thrive remarkably well as annuals across Canadian growing zones when given an early indoor start and proper spring vernalization.

In milder zones or sheltered microclimates (like Zone 6+), plants can be overwintered by cutting back foliage in late autumn and applying a heavy 12-inch layer of straw or leaf mulch over the root crown.
