About Symphyotrichum eulae (Shinners) G.L.Nesom
Symphyotrichum eulae (Shinners) G.L.Nesom is a perennial herbaceous plant. It reaches heights between 5 and 150 centimeters (2 to 59 inches), growing from a long, thick rhizome and forming colonies. Each individual plant in a colony produces one to three or more erect, straight, stout, glabrous (hairless) stems. The flowers have white to bluish or lavender-white ray florets, and disk florets that are yellow before changing to reddish or brown. This species is endemic to Texas, United States. It was originally recorded by Shinners from the Texas counties of Bexar, Calhoun, Cooke, Dallas, Denton, Hill, Hunt, Kaufman, Navarro, Rockwall, Tarrant, Wise, and Wood. In his 1950 protologue for the species, Shinners noted it was "Common in north central Texas, from Hopkins and Wood west to Cooke and Wise counties; extending south to Bexar and Calhoun counties". Symphyotrichum eulae grows in semi-shaded clay or sandy clay soils at elevations up to 100 meters (330 feet).
