Black-Eyed Susan

Rudbeckia hirta 'Denver Daisy'

Summer long flower power with great heat tolerance on this sturdy coneflower.

Gloriosa Daisy hybrids are short-lived perennials, sometimes treated as annuals. Often these will survive a few winters, or at least self seed. This midsized strain produces large golden-yellow daisies, the black cone surrounded by a big mahogany-red eye. Flowers for months on end, on a compact, bushy plant. An outstanding cut flower. Removing faded blossoms regularly will greatly increase the flowering time. Seed heads have good winter interest, and can be used in dried arrangements. Fairly drought tolerant, once established. Wonderful in mixed containers. Bred by Ernst Benary Seeds to commemorate the 150th anniversary of Denver, CO.
