      Piercing, bright blue flowers with ruffled petals and violet-blue centres appear from early to late summer among lance-shaped, mid-green leaves.

The flower petals are edible and have a clove-like taste.

“Full, cobalt- blue thistles on stiff branching stems top jagged silver foliage on this giant, architectural cardoon that revels in hot sun”
