Bear'S Breech (Acanthus spinosus)

Description

Acanthus mollis reaches on average 30-80 centimetres (12-31 in) of height, with a maximum of 180 centimetres (71 in), inflorescence included. It has basal clusters of deeply lobed and cut, shiny dark green leaves, soft to the touch, up to 40 centimetres (16 in) long and 25 centimetres (9.8 in) broad, with a long petiole. The inflorescence is a cylindrical spike 30-40 centimetres (12-16 in) long and can produce up to 120 flowers. The flowers are tubular, whitish, and lilac or rose in colour. Each flower is up to 5 centimetres (2.0 in) long and it is surrounded by three green or purplish bracts. The central bract is spiny and larger than the other two. The calyx has two lips: the upper is purple on top, rather long and forms a kind of "helmet" on top of the corolla. The corolla is reduced to a white lower lip, trilobed, with purple-pink venation. The four stamens are fused to the corolla and look like tiny brushes. This species flowers in late spring or early summer, from May through August.
