Rudbeckia hirta, commonly known as Coneflower.
A really nice variety is Rudbeckia hirta Prairie Sun. This unique daisy plant was awarded a Fleuroselect Gold Medal. It looks really lovely in beds and borders. The unusual blooms with central green cones and bright orange petals radiating back to lemon yellow, make dazzling cut flowers.
NOTE: This Coneflower genus of plants includes black-eyed and brown-eyed Susan and Golden Glow.
