Summary

Acanthus mollis, commonly known as bear’s breeches, is a perennial herb native to the Mediterranean region, specifically found in scrub and woodlands. It is characterized by its glossy, deeply lobed leaves and tall flower spikes with purplish and white flowers that bloom in early summer. The plant typically reaches a height of 3-5 feet (0.9-1.5 meters) with a similar spread. The flowers are showy and add architectural interest to garden borders.

Bear’s breeches are valued for their striking foliage and flowers, which can add a classical touch to garden designs, reminiscent of the plant’s frequent depiction in ancient Greek and Roman art. It is used in borders, as a focal point, or in cottage gardens. Acanthus mollis prefers well-drained soil and can tolerate a range of light conditions from full sun to part shade. It can become drought-tolerant once established. It can spread by rhizomes and self-seeding, which may become problematic if not managed. It has been found to become invasive in western Europe, parts of the Americas, Australia, and New Zealand.CC BY-SA 4.0
