It is Passiflora x belotii, or Passiflora alata x caerulea, a completely sterile hybrid.

Thanks. I figured it out this morning. I'd remembered seeing a similar flower posted a week or two ago so I looked through the old posts. I didn't know it was sterile, too bad, it's pretty. I wish I could get close enough to smell it but it's too high up on the fence.
