Noteworthy Characteristics

Rudbeckia is a genus of about 20 species of annuals, biennials and perennials from North America. They are grown for their showy flowers.

Genus name honors Olof Rudbeck (1630-1702) Swedish botanist and founder of the Uppsala Botanic Garden in Sweden where Carl Linnaeus was professor of botany.

‘American Gold Rush’ is a naturally compact cultivar (a bit more compact than 'Goldsturm') with narrow 2 inch wide hairy foliage bred for its resistance to Septoria leaf spot. Gorgeous bright, yellow-gold flowers bloom from July to September. The cultivar has smaller foliage and shorter height compared to its seed parent, Rudbeckia fulgida var. deamii. US Plant Patent PP28,498 awarded October 3, 2017 to Intrinsic Perennial Gardens.

Problems

No serious insect or disease problems. Taller plants usually need staking.
