Echinacea 'PowWow Wild Berry' 2010 AAS Flower Award Winner This AAS Winner differs from other coneflowers for flower color, branching and plant size. The incredibly vivid deep rose-purple flowers retain color longer. This first year flowering perennial has superior performance including a basal branching habit that results in more flowers per plant. Expect rapid and uniform flowering at a day-length of 14 hours. Reaching a mid-height of 20-24 inches in the full sun garden, it will bloom continually without deadheading or grooming.
