The Story
Plant Bio
Acanthus mollis, bear's breeches, is a bold clumping perennial native to Europe and North Africa, reaching three to six feet in flower. Its glossy dark green leaves are deeply lobed and cut, up to sixteen inches long, forming a substantial basal mound, and tall spikes carry hooded white and purple flowers above them in early summer.
Those leaves are the model for the acanthus motif carved into Corinthian columns, and they carry small spines along the lobes. It is very difficult to remove once settled — any root fragment left in the soil regrows — so site it deliberately and treat it as permanent rather than something to move later.

Planting
How to Grow
- Plant in spring in deep, well-drained soil.
- Choose full sun to partial shade; afternoon shade in hot climates.
- Allow two to three feet of width.
- Water through the first season, then sparingly.
- Site it permanently; root fragments regrow.
- Cut spent flower spikes and tatty leaves in late autumn.
Pro Tip
Plant it where you want it forever — every root fragment left behind resprouts, so moving an established clump usually means having it in both places.
