It looks like Passiflora 'Aragorn' (P. kermesina x P. aff. oerstedii).

I have alot of the butterfly food ones but I do love the hard to get ones with neat flowers I have loss a few do to the heat but passiflora are very easy to grow were I live so I get all I can find love to be suprised when they finally bloom.

Absolutely P. "Aragorn".

Hi all, I was just browsing and came across this post. Actually, I think that this flower is NOT Passiflora 'Aragorn'. Rather, it appears to be one of the several varieties of Passiflora "Pura Vida". See the following links for examples:

Though I could be wrong, what makes me think that this is Pura Vida and not Aragorn is the light-colored center - I believe Aragorn has a much darker center. In any case, you may have already figured this out, but for someone just surfing the web, this disambiguation may be useful.

Happy gardening!

"Disambiguation"---now THERE'S a word you don't see very often. (*grin*)

Always tricky to ID from just one picture, but I think Mikulas is right that it is one of the Pura Vida variations, often called P. 'Pura Vida' purple. The leaves also look correct.
