I believe this flower belongs to the Columbine family, although I might be mistaken. I must admit that I have a very limited knowledge of flowers. I just like playing in dirt (although doing so causes me great lower back pain) and photographing the fruits of my labor!
Note: Sometimes I will check my photo postings on a computer at my local library to check their quality on a different computer than my own. On two occasions, I have noted the quality of my photographs severely lacking. This post was one of them. If I was fortunate to have you view my work and you found the quality poor, please let me know via a viewer comment.
