Normally grown as a culinary delicacy, but also a very ornamental large perennial. Very large, jaggedly cut, silvery green basal leaves. Strong stems rise to carry the big, thistle type flower heads, with scaly bracts enclosing the purple-mauve tufted flower.
Moist, well drained soil and full sun. Best in light soils and a reasonably warm location sheltered from cold winds.
In cold areas the rootstock should be protected by a dry winter mulch.
From seed or by division of suckers
A culinary delicacy and also an important medicinal herb since ancient times, still used for the treatment of digestive and liver problems.
For edible use, the flowering buds are cropped before they open.
Probably originates from North Africa but now widely cultivated.
