Gardeners' Notes:

Positive coriaceous On Dec 25, 2014, coriaceous from ROSLINDALE, MA wrote:

This plant's chief claim to fame is its continuous bloom from June to frost. The flowers are magenta-rose and self-cleaning. The flower display is attractive, long and continuous but never overwhelming. The foliage is fine-textured and handsome.

Easy, vigorous, deep-rooted, clump-forming, tough as nails. Very drought-tolerant once established, this is a xeric plant and should not be over-watered. No pests or diseases here---the foliage stays clean and healthy till frost. Not particular about soil, as long as it's well-drained, and it fixes its own nitrogen.

This is a suckering woody plant with an upright habit, whose top growth my Z6a winters kill to the ground. The only care it needs is to be cut to the ground in the spring (perhaps better in fall after frost). It's late to emerge from dormancy in the spring, so don't be quick to assume it's dead when spring comes. Established plants get about 3' tall in the course of one season here, but in some milder climates (England) where the winters don't kill the top growth this can get to 8' or so.

Clump-forming, it suckers but is not an aggressive spreader.

The Royal Horticultural Society has granted this species its coveted Award of Garden Merit.

This is said to be hardy to Z5a.
