These plants are unsurpassed for the strong, sculptural effects they create with
mounds of long dark green arching foliage. The plant has large oblong leaves which
can be variously cut, lobed, or even deeply pinnately divided.
The irregular and unusual flowers form on stiff erect spikes well above the foliage.
The corolla is tubular, with a large 3-lobed lower lip. It is suspended by
spine-tipped bracts and a large calyx lobe; another enlarged calyx lobe forms a hood.
Acanthus usually flower in late spring to early summer in the warmer regions, and
midsummer elsewhere. Flowers can be white, lilac-pink or purple tinged.
