A stout, upright perennial native to Texas extending north throughout the central plains states. Numerous bright yellow 3 inch flowers are found on the upper half of unbranched stems. The leaves are 4 to 8 inches in length, tapering at both ends. Soil fertility and the amount of moisture will determine the height of the plant.
