DALLAS -- Bluebonnets, bluebonnets everywhere. The state flower is out in full force. Five species of Texas bluebonnets dot the state. Their prevalence along 79,000 miles of state highway is no accident. The Texas highway department began planting seeds along roadways in 1930. They now sow more than 33,000 pounds of wildflower seeds, including bluebonnets, each year. Late March through early April is the best time for viewing roadside fields of blue. Viewing locations stretch from the Rio Grande Valley north to Childress. For more information Texas Department of Transportation wildflower map or call the wildflower hotline at (800) 452-9292.
