Typically artichokes are perennials in zone 7 and above but the Imperial Star Artichoke variety was bred specially for northern climates to produce well developed buds in the first season. A vernalization is required in the north for first year buds set the seedlings out for 10 days at temperatures of 45-50 degrees. This tricks them into thinking they have gone through a winter and they will produce like a 2 year old plant. The flavor of fresh artichokes is superior to anything you will find in the store. Sow seeds in the fall if you live above a zone 7 area.

12 seeds

PLANTING

Cynara scolymus

Germination:10-18days

Germination Temperature:Optimum soil temperatures 70-80F

Seed Sowing Depth:1/2″ deep

Sowing Indoors:8-12 weeks before the last frost.Sow 2-3 seeds per cell/pot. Sowing into individual biodegradable peat/cow pots reduces rootdamage when transplanting. Before transplanting outside, vernalization is required for growth in the north (zone 6 and below). To induce first-year bud formation, set the seedlings out for 10 days at temperatures of 45-50F. Transplant after last frost, 24-36″ apart

Sowing Outdoors:Sow Imperial Star Artichoke seeds in the fall if you live in zone 7 and above.

Harvest– Just below the bud when they are firm and still closed

Tips– Artichokes are heavy feeders and need fertile well-drained soil. Amend soil with compost or well-rotted manure before planting.
