Rudbeckia hirta

Common Name(s):
Black-eyed Susan, Gloriosa daisy
Cultivar(s):
Sonara, Indian Summer
Categories:
Annuals, Perennials, Wildflowers
Comment:

A 2 – 3 foot stiff, upright annual or short lived perennial native to the eastern United States, but has become endemic throughout North America. The characteristic brown, domed center is surrounded by bright yellow ray florets.  This is a true sunshine worshipper that forgives neglect and has moderate drought tolerance.

The trick to growing black-eyed Susan is to give it full sun in decent soil. Moderate fertility will give you the best flower show so avoid the edges of lawns where lawn fertilizer will provide excess nitrogen.
