Petals are re-flexed back where many of the new coneflowers are flat. So its' got the old-fashioned look but with better flowering, good vigor and a vibrant red color. Nicely compact - good toward the front of the border. This would look lovely combined with blues such as Russian Sage, Blue Chip Buddleia and a host of other perennials.
