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



Cynara scolymus

Germination: 10-18 days

Germination Temperature: Optimum soil temperatures 70-80ºF

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 root damage 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 45-50ºF.  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.
