Globe artichoke

Cynara scolymus

A Mediterranean thistle relative grown as a perennial vegetable for its large, unopened flower bud — the edible "globe" of overlapping fleshy bracts harvested before bloom. It forms an upright clump of deeply lobed, jagged silver-green leaves, with flower stalks rising to 3-5 feet. Left unharvested, the buds open to spectacular violet-blue thistle flowers up to 7 inches across that are a magnet for bees.
