Black-Eyed Susan (Rudbeckia Hirta) - This familiar, yet gorgeous golden yellow wild flower is often seen growing in large colonies along highways, in fields, and in many natural settings. Black-Eyed Susan easily establishes from Rudbeckia Hirta seeds, and it produces clumping, stiff, upright plants that are short-lived. Rudbeckia Black Eyed Susan is native to the eastern United States and is probably the most common of all American wildflowers. They have the characteristic dark brown, domed center which is surrounded by bright, golden yellow petals. Black-Eyed Susan wildflowers thrive in most soils, in full sun, and they forgive neglect.
Black-Eyed Susan grows perfectly in gardens, in borders and in flower beds, and it is a great summer time bloomer. Butterflies of many species are attracted to its bright blooms. It grows in all regions of North America in any soil from sand to clay, but it must have full sun. Black-eyed Susan care includes deadheading to prolong the bloom season, but the plants will re-seed themselves readily if you leave a few blooms to go to seed.
Sow Black-Eyed Susan wildflower seeds outdoors any time in the late fall or as early in the spring as the ground can be cultivated. Prepare soil by loosening the top 1 - 2 inches and removing any weeds. Sow the Rudbeckia Hirta seeds into the loosened soil and rake in. Walk over the area to gently press the wildflower seeds into the soil. Keep the Black Eyed Susan seeds moist until germination. Rudbeckia plants transplant well and should be spaced 12 - 18 inches apart. The Black Eyed Susan plant forms a clump that will reach 12 inches in width. Considered a biennial, it will not bloom much the first year the flower seeds are sown. The following year will bring many more blooms. The seed is small, but it is considered to be very easy to grow. Rudbeckia Hirta seeds are a staple of any good wildflower seed mixture and the golden yellow blooms are a major color-maker in any wild flower garden.
