The purple spikes of flowers bloom on striking black flower stems. These are valuable plants where summers are hot because they ignore the heat and stick with the business of making flowers.

This sturdy perennial is as tough as they come. Clumping foliage displays large, plate-like flower clusters that start pink, then gracefully age to rosy russet-red in the fall. A fine addition to the rock garden or mixed border. Succulent foliage will die back to the ground in cold winter regions, but will re-emerge in early spring.
