Prima Ruby Coneflower
Rich Ruby-Rose Daisies on a Dwarf, Front-of-Border Coneflower
Prima Ruby Coneflower (Echinacea 'Prima Ruby') covers an ultra-compact, mounding plant with deep ruby-rose daisies. The Prima series is among the shortest coneflowers available — dense, tidy, and floriferous from early summer into fall — perfect for the very front of the border and containers. Bees and butterflies love the blooms, and goldfinches enjoy the fall seeds. Drought-tough and deer-resistant, it's a jewel-toned little gem for sunny spots in Edina, Eagan, and Maple Grove.
