Acanthus are large, bold, structural plants that deserve a solitary position leaving enough space for them to develop and mature to full size (150 cm in diameter). The thistle – like dark evergreen leaves were the templates for the ornamental carvings of ancient Greek columns. Once planted do not move again as they will grow and spread from remaining roots. Good companions are plants with a similar habit, like Melianthus and Romneya.
The attractive tall flower spikes look well all Summer and Winter and are popular cut flowers.
