The Perennial Plant Association is pleased to promote Rudbeckia ‘American Gold Rush’ as the 2023 Perennial Plant of the Year. ‘American Gold Rush’ is a stunning addition to any garden. At the height of summer, it turns up the volume for a long season of dazzling color right up to autumnal frosts. The bright golden-yellow flowers feature arching rays and a reddish halo surrounding dark chocolate cones. Three-inch flowers blanket the compact plant, which is only 22-27 inches tall with a broader width to 40 inches if given room to grow.
The green leaves and stems are covered in hairs, which gives them a silvery cast — on sunny days, peeking through the blooms to the leaves is a luminous silver-and-gold treat. More than just boosting the ornamental show, the hairy foliage is resistant to Septoria leaf spot — a debilitating fungal disease that causes unsightly black spotting and premature seasonal decline on some Black-eyed Susans. ‘American Gold Rush’ is a reliable hardy perennial and a great substitute for popular, brassier ‘Goldsturm’, which is highly susceptible to leaf spotting.
