This bold, architectural perennial is a favorite of designers and collectors. Its huge, shiny, dark green leaves form a basal mound topped with impressive spikes of large, hooded, mauve and white flowers. Nearly evergreen in warmer climates. Mulch for winter protection in the north.

Grown for its bold foliage and impressive flowers, this striking perennial forms a sizeable clump of dark green, thistle-like foliage topped with huge spikes of large, mauve and white flowers. It is a bit hardier than A. mollis and thus produces a showier floral display in cold climates. Non-aggressive spreader.
