One of the most exciting recent developments in plant culture has been the "Big Sky" series of coneflowers--crosses between the Echinacea purpurea and Echinacea paradoxa species. The results are coneflowers in new colors from yellows to oranges to reds. The curious color tone of this 'Sundown' coneflower is transitional, as the blooms turn from pink to bright orange to soft purple-pink. This plant can reach 30 inches tall and 24 inches wide and thrives in full sun and average to dry soil. If you find one, snap it up, because they tend to sell out early.
