Black eyed susan is a gorgeous gold wild flower you see everywhere. You will often see it growing on its own, often in great golden sheets of color along the highway, in unused fields, and often in your own backyard. A stiff, upright annual or short-lived perennial (perennial in some places, biennial in others) native to the eastern United States, but has become endemic throughout North America. The exact way black eyed susan performs depends on where you live. It usually grows as a biennial, which means it takes two years to bloom from wild flower seed. Biennials live only two years, and bloom only their second season, then die after reseeding heavily. However, in some regions, black-eyed susan grows as an annual, blooming the first year. In other areas, experts believe it is a perennial. The black-eyed susan is probably the most common of all American wildflowers. The characteristic brown, domed center is surrounded by bright yellow ray florets. Thrives in most soils in full sun. A true sunshine worshiper that forgives neglect.

Black eyed Susan grows perfectly in gardens, in borders and in flower beds. Black-eyed susan is a good summertime bloomer. Butterflies of many species are attracted to black-eyed susan. Grows in all regions of North America in any soil from sand to clay, but it must have full sun. You can plant it in the spring, summer, or fall. Black eyed susan wildflower seed is very small; therefore, do not cover the seed more then 1/16th of an inch. Simply broadcast the seed over the desired area and press or roll seed into loosened soil if possible. The seed may be small, but for wild flower gardeners, it is a snap to grow from wildflower seed, and is a staple of any good wildflower seed mixture. Because these beautiful flowers can easily be one of the major color-makers in any North American wildflower garden.
