Anna, saw "Bluebonnets", and missed "Mtn. Laurel" in your post. Yes, those are Mtn. Laurel blooms. They smell like grape soda to me!
Well, our hills also go down to the highway. Possibly, a little warmer along I35 with all those semis and stalled traffic kicking up some heat! I think we may be a little disappointed in the bluebonnets if we get much more rain. All those wildflower seeds that get thrown out to make the highways so beautiful, sometimes grow faster than than bluebonnets and block the sun from the bluebonnets. "No good deed goes unpunished."
