ADDITIONAL INFORMATION :Perennial. To get artichokes the first year, start indoors in a warm place, then harden off and transplant outside while weather is still cold, so the plant thinks it's been through the winter. Or plant out after frost and get chokes the 2nd year. Artichokes like good soil and good drainage. Give the crown protection from cold and wet, planting on a slight mound and working in compost and some sand or gravel near the surface.
