Texas Bluebonnets in the Sun – Texas Bluebonnets in the sun are always more brilliant and appealing to the passer-by. As soon as the grasses start to grow in the spring the roadside mowers try to get all the right of ways mowed pretty short. Then, when the wildflowers come up they can stay ahead of the grass for several weeks. This approach allows folks to enjoy the flowers longer. Sunny days really bring out their beauty.
