The best bluebonnets I've seen this year were in the Austin city limits on the steaper hillsides, not much in the Hill Country (I live west of Austin and work in town).
Texas Paintbrush are just about finished.
Indian blanket, Mexican Hat, Coneflower, and Black-eyed Susans seem pretty thick this year and are really starting to come out. Celestials are pretty thick as well.
On a side note, this was the best year for the Mountain Laurels I've seen in a while.
