Yes bluebonnets! They are so beautiful. They typically grow with Indian paintbrushes seen in this picture. This is a pic from Google, but this is exactly what it looks like in my neck of the woods when they are in bloom. OMG, it is just the best feeling to go driving on the oil tops to spot them. Bluebonnets family portraits are a must here and everyone does it every year.
There are a lot of themed family portraits, for almost every holiday. I didn't think this was a Texas thing and thought everyone did it.
