Cardoon

Cynara cardunculus
A stately, clumping perennial, reaching up to 6 x 4 ( rarely over 5 ) feet, that is native to the southwestern Mediterranean region.
The arching, deeply-lobed and toothed, thisle-like leaves, up to 3 feet in length, are gray-green.
The thistle-like purple flowers, up to 3 inches wide, are borne during mid-summer.
Hardy zones 8 to 9 ( 7 on protected sites and mulched with thick pine boughs during winter ) in full sun on moist, fertile, well drained soil. Propagation is easy from seed. Clumps can also be divided during early spring. The unopened flower heads can be boiled and eaten like artichokes.
