Imperial Star Artichoke (90 Days)

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: 10-18 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.
