The globe artichoke is a member of the Composite family, closely related to the thistle. The edible part is from the immature flower bud. If the buds or “globes†are not harvested, 6 inch bluish, thistle-like flower heads develop. The edible portion of the “globe†is composed of the fleshy bases of the flower bracts and the receptacle to which the bracts are attached, known as the “heart.â€The 'Colorado Red Star' artichoke is an easier-to-grow variety that can be grown from seed as an annual. It produces high yields of green/purple to fully purple heads .
