I'm at 700 ft. altitude, and am hoping this overwinters well. I'm in Zone 8b that sometimes is more like 7a, so I've lost some things over the years believing the Zone Map. But this spread quickly, and has made a weed barrier that is better than any other I've experimented with.

Covered with bright coppery orange-red flowers in Jun-Jul, over fat gray-green evergreen leaves. Sheer after bloom to maintain shape and encourage subsequent more sporadic blooming. Drought tolerant. I grow this in a very hot & dry west facing rockery garden in front of sedums. Nice combo.

May die back and regrow in colder regions, be evergreen in the warmer. Brilliant red-orange flowers over grey foliage. It requires excellent drainage, especially in the winter. It settled in much more quickly than the 'Wisley Pink' variety.
