It would be hard to find a perennial more bold and statuesque than the cardoon. This relative of the artichoke can rise to six feet or more and has large, coarse, grey-white stems and leaves. The plants are topped with large, mauve thistle-like flowers in summer. Use as a focal point in the garden. From Mediterranean Europe.
