Hello @ steemgold: as I had the doubt about the name of this particular flower that you published, I started to research a bit on the internet and I think the name of the flower is "Butterfly pea" (Centrosema virginianum - Family: Fabaceae), the which grows in human disturbed areas such as abandoned fields and along the edges of Dry Broadleaf Evergreen Formation-Forest / Shrublands (coppice). Anyway, here I leave the link: http://www.levypreserve.org/Plant-Listings/Centrosema-virginianum ...Greetings
