White Flower Farm
Acanthus spinosus
Best architectural perennial for gardeners seeking dramatic, deer-resistant vertical interest.
Acanthus spinosus, or Bear's Breeches, offers striking architectural foliage and bold floral displays. This perennial forms sculptural mounds of deeply cut, thistle-like leaves, often evergreen, providing year-round interest. In early to midsummer, it sends up impressive spikes of white flowers framed by spiny bracts, adding vertical drama to the garden. Its handsome leaves, reminiscent of ancient Greek designs, make it a unique specimen plant. Both flowers and seedpods are excellent for cutting, bringing lasting beauty indoors. It thrives in full sun to part shade with moist, well-drained soil.

Know before you buy
In warmer climates within its hardiness range, the foliage typically remains evergreen. In colder zones, the leaves may die back during winter but will reliably return in the spring.
Because this perennial grows into a substantial sculptural mound, you should space plants at least 4 feet apart. This allows enough room for the foliage to spread and ensures proper airflow.
Acanthus spinosus thrives in moist, well-drained soil. If your garden has heavy clay, amend the soil with organic matter to improve drainage and prevent the roots from sitting in standing water.
Yes, both the impressive white flower spikes and the subsequent seedpods are excellent for cutting. They add a dramatic, architectural element to floral displays and hold up well once cut.
Acanthus spinosus is considered deer resistant, making it a reliable choice for gardens where deer pressure is a concern. While no plant is entirely deer-proof, its spiny, thistle-like leaves are generally unappealing to them.
Plant your bareroot specimen in a hole large enough to accommodate the roots without crowding. Ensure the crown is positioned just below the soil surface and water thoroughly after planting to help it establish.
