Rudbeckia hirta The Gloriosa Daisy is not a true daisy, but has daisy like flowers. It is in fact of the same species as Black Eyed Susans. 3' tall plants produce large colorful blooms. Flowers are burnt red in the center turning golden orange-yellow towards the tips. Easy to grow, loves full sun but will tolerate partial shade and is heat and drought tolerant. A great cut flower, keeps well in floral arrangements. Biennial, but blooms in first year.
