  • History & Lore
    This great wildflower of North America is among the famous group of coneflowers that inhabit the prairies. The black eyed Susans are the first to become domesticated garden flowers. The genus was classified by Linnaeus who chose to name it in honor of his mentor and friend Olof Rudbeck, 1660-1740. There are over 30 species native to America and this species is found in moist meadows of Michigan south to Missouri and est Virginia. The species was classified by English botanist William Aiton, 1731-1793. 'Goldstrum' is an old German seed strain that has proven far better under cultivation although it is hotly depated whether there is differences between R. f. var. sullivantii and Goldstrum.
