Rudbeckia x hirta hybrida 'Cherokee Sunset'®

Shades of golden yellow, orange, bronze and mahogany make up this stunning blend that resembles the attractive colour spectrum of an Indian Sunset. Vigorous, free branching plants, with strong stems, which flower over a long period from mid summer to early autumn.
