Acanthus mollis offers unusual pink-mauve flower spikes with white interior petals and purple calyces, held 3' to 4' above deeply lobed large shiny leaves. Bear's Breeches grows best in part shade and in a moist protected spot in the landscape. Too much shade will result in less or no flowers. This clump-forming perennial is grown as much for its attractive foliage as for its architecturally bold flower spikes. Native to the Mediterranean region, it flowers in late spring to mid summer with multiple vertical flower spikes. The leaves were the source of the Corinthian leaf motif developed and used as a decoration in ancient Greek and Roman art and architecture.
