Bluebonnets growing alongside an old road in the Texas Hill Country

Where the wildflowers grow

In honor of National Wildflower Week, we're looking at a splash of blooming bluebonnets, the state flower of Texas. If you notice bluebonnets and other blooms while traveling down Texas highways, thank the state's Department of Transportation, which sows tens of thousands of pounds of wildflower seeds along roadways each year.

But wildflowers aren't just pretty to look at. Most of these native plants grow on their own—without the need for cultivation—helping preserve water, protect against erosion, and provide habitat for birds, butterflies, and other critters. Plus, they have a restorative quality for the mind, just as wildflower-lover Lady Bird Johnson once said: 'Where flowers bloom, so does hope.'
