Rudbeckia texana

Rudbeckia texana, commonly known at Texas coneflower or shiny coneflower, is a perennial plant in the family Asteraceae native to the Western Gulf coastal grasslands of Texas and Louisiana.

Flowers have a conical shape and are about 2.0–4.5 cm tall, 1–1.5 cm wide with yellow ray florets circling a conspicuous dark brown dome-shaped cone of many small disc florets.

[1][2] Because of its morphological differences from Rudbeckia nitida, R. texana was elevated from varietal to species level in 1989.

[2] Rudbeckia texana can be found in western Louisiana and eastern Texas, primarily in remnant wet prairies and along railroads and highways.

[3] The Texas coneflower is sensitive to overgrazing, plowing, and other forms of degradation.
