Bear's Breeches

Acanthus spinosus

Plant Details:

Plant Type: Perennial
Plant Family: Acanthaceae
Plant Description: This plant has a clumping habit but can spread aggressively by creeping rootstocks. The leaves are glossy green with spiny, thistle-like leaves that arch to the ground. The flowers are pure white snapdragon-like flowers with reddish-purple hooded look. Flower spikes are 3-4 feet tall. They prefer average, well-drained soil and should not be overwatered.

Maintenance:

Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
