Echinacea paradoxa, the yellow coneflower[2][3] or Bush's purple coneflower,[4] is a North American species of flowering plant in the sunflower family. It is native to southern Missouri, Arkansas, and south-central Oklahoma, with one isolated population reported from Montgomery County in eastern Texas.[5] It is listed as threatened in Arkansas.[4][6]
Echinacea paradoxa is a perennial herb up to 90 cm (3 feet) tall. One plant can produce several flower heads, each with white, pink, or yellow ray florets and pink or yellow disc florets.[6][7][8][9]
- Echinacea paradoxa var. paradoxa - yellow rays - Arkansas and Missouri
- Echinacea paradoxavar.neglecta - pink or white rays Oklahoma and Texas
Echinacea paradoxa var. paradoxa has a baseline chromosome number of x = 11, like most Echinacea plants.[10]
