purple flower~Today's Flowers 021311

I have two of these blooming in my front yard and honestly, I don't remember what they are! Texas bluebonnets? I was just so happy that they grew! I'll try to go out today and get more photos of them. Anyway, I thought this one was pretty and I decided to post it for today. Today's Flowers for Sunday, February 13, 2011. Please let me know what it is if you know! Desert lupine? Texas bluebonnet?
