Acanthus are easy to grow plants that prefer a partially shaded spot as full sun can harm the leaves, they can be grown in full shade but may flower a little less. Grows well in most soils, provided they are well-drained. During the first year water regularly but once established they are drought tolerant. A balanced fertiliser can be applied in spring or mid-summer if the plant looks like it needs it. Remove faded flower stems after flowering and any tired looking leaves in spring. Keep a look out for slugs and snails as they are partial to the leaves.
