Rudbeckia or gloriosa daisy varieties offer sizzling bright oranges and golds, plus subtle pastel color schemes and even deep red and chocolate hues. A must for wildflower gardens combined with grasses and coneflowers and valuable in the cutting garden and border for mid-summer through fall bloom. Deadhead for more flowers and mulch to conserve soil moisture during high summer. May overwinter in zones 5-8, but most often grown as an annual. Self-sows.
