Acanthus spinosus is a statuesque architectural plant, with handsome dark green leaves whose stylised shapes form the decorative detail on Corinthian columns, bringing a strong hint of classical elegance to the garden. The plants make large, mound-shaped rosettes of glossy leathery leaves, finely cut and each tipped with a ferocious spine. The flower spikes resemble tall foxgloves from a distance, with hooded two-tone flowers. Once established it is virtually impossible to move plants so correct positioning is vital. A dramatic plant for growing in gravel or grass, or at the back of a large border. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).

Grow Acanthus spinosus in moist but well-drained soil in full sun to partial shade. Cut back after flowering. For a similar plant, but with bolder leaves, try Acanthus mollis.
