Bear's Breeches Overview
Acanthus is a genus with around 30 species of herbaceous, perennial flowering plants from dry rocky Mediterranean landscapes. Some are semi-evergreen and grown for their ornamental flower spikes and lobed, toothed, sometimes spiny leaves, which can reach up to 90cm long. They are fully hardy and the tubular flowers produce nectar so these species make great garden plants for attracting pollinators. The 3.5-5cm flowers have 2 lips (perfect for insects to perch on!) and are borne generally in ranks of 4, on upright, unbranched spikes, growing to around 1.2m high. One of the most well-known plants from this genus is Acanthus mollis, commonly known as Bear's Breeches. This common name is shared with multiple plants in the genus Acanthus.
