Acanthus spinosus is native to the Mediterranean and can tolerate most garden conditions other than poorly drained soils. It can withstand full sun, but may preform best with late afternoon shade. It has showy vertical reddish-purple flower spikes that are held above the foliage, which is an attractive glossy green. Although slow to establish, it can spread by creeping roots if not kept in check.
