Where the wildflowers grow © Inge Johnsson/Alamy
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.
