Description

Emerging petals on this Black-Eyed Susan wildflower are reaching for the sun! Rudbeckia hirta, the Black-eyed Susan, with the other common names of: Brown-eyed Susan, Brown Betty, Brown Daisy (Rudbeckia triloba), Gloriosa Daisy, Golden Jerusalem, Poorland Daisy, Yellow Daisy, and Yellow Ox-eye Daisy. It is a flowering plant in the family Asteraceae. It is an upright annual (sometimes biennial or perennial) native to most of North America, and is one of a number of plants with the common name Black-eyed Susan with flowers having dark purplish brown centers. Black-eyed Susans can be established, like most other wildflowers, simply by spreading seeds throughout a designated area. They are able to reseed themselves after the first season. The Black-eyed Susan which means �Justice� makes a very nice cut-flower with a vase life up to 10 days. The genus name honors Olaus Rudbeck, who was a professor of botany at the University of Uppsala in Sweden and was one of Linnaeus's teachers. The specific epithet refers to the trichomes (hairs) occurring on leaves and stems. The plant can reach a height of 1 m. It has alternate, mostly basal leaves 10-18 cm long, covered by coarse hair. It flowers from June to August, with inflorescences measuring 5-8 cm in diameter (up to 15 cm in some cultivars), with yellow ray florets circling a brown, domed center of disc florets. black-eyed susan, wildflower, yellow, petals, closeup, nature, plains, prairie, dakota #201007160218
