It is very impressive as an ornamental herb plant. It is tall and stately with large, mottled, spiny foliage that contains a milky sap-like substance and large, thistle-like heads of rose-pink flowers. Milk Thistle herb plants do re-seed themselves, so it is recommended to deadhead the flowers before they set seed. Other common names for this herb plant are Mediterranean Milk Thistle, Marian Thistle, St Mary's Thistle and Holy Thistle.
