Texas Wildflowers

List of Texas species featured in Texas Wildflowers by Campbell and Lynn Loughmiller. For two decades and counting, Texans have relied on Texas Wildflowers to identify the common and rare flowers we see along the roadsides and in the pastures, fields, and forests of our state. Compiled by naturalists Campbell and Lynn Loughmiller, with the technical assistance of Lynn Sherrod, Texas Wildflowers is an authoritative field guide with a personal touch in the many notes the Loughmillers included about the plants they described and photographed.
