Glow & Blooms

Alright, so I took this shot a few months ago while on an outing to Desoto Falls with Rachel. I have no clue what type of flower this is but it was really pretty. The photo doesn't really do it justice. I've never exactly seen anything just like it. It was glowing in a Church garden in Alabama so I'm not sure if it was planted there or if it grows wild. Any thoughts?
