Description

Spiny Bear's Breeches (Acanthus spinosus) is a clump-forming perennial that is grown as much for its attractive dark green foliage as for its architecturally bold flower spikes. The foliage of this species deeply cut and rather spiny looking dark-green leaves without actual spines. Flowers are creamy white (sometimes pinkish) and snapdragon-like and DO have sharp spines! It is the most thistly-looking of any of the various forms available. Foliage is mostly evergreen in warm winter climates, but plants lose their leaves when winter temperatures dip below 20°F. Foliage is usually persisting until mid-early December in Kansas. If low temperatures hit -10 degrees F, it may kill an un-mulched plant; protect any zone 6 perennial with thick layer of mulch. Established plants survived -16 degrees F and a week of single digit highs in February, 2021.
