Black-Eyed Susan are perennials from open spots in prairies and sunny mountain meadows in North and Middle America. They develop numerous and very colorful, bright yellow flowers on medium to tall stalks throughout summer. Many species are excellent cut flowers. Rudbeckia are easily cultivated in any rich, well drained soil in a sunny spot. They are very robust and adopt very well to various soil types.
Sow flat in any rich, well drained soil. Keep pots in a sunny , protected spot outside. Several species require a cooling period of several months prior to germination. If these species are sowed late in the year, they do not germinate before spring in the following year. Transplant to the final spot in the garden in late summer to autumn.
All are USDA Climate Zone 6.
