Acanthus mollis or the Oyster Plant is a clump forming, herbaceous perennial with dark green, glossy, deeply serrated leaves that are about 1m long and arch outwards.
White/mauve flowers appear in mid summer along the top part of a long spike.
This plant is good for filling those difficult shady spots and makes a good contrast in the middle of deep, mixed borders.
Perfect for informal and cottage style gardens.
