This is most likely Ipomoea nil and I'm not aware of any blue colored Calystegia species anywhere...

Thanks for helping me identify the flower Selma. I just googled some images .It's Calystegia spp indeed.:) this lovely flower .. But the image in your profile is lovelier :)
I was just curious about these beautiful flowers blooming on the roadside while i jogged last weekend.
