@greene it must have been P. coccinea since the leaves he provided were not lobed and @Ursula advised that P. vitifolia has three lobed leaves. @Ursula is surely correct since the common name for P. vitifolia includes 'grape leaved Passion Flower' if you search enough. The leaves Glen provided in his photo don't resemble grape leaves, for sure . I concluded his plant to be P. coccinea from the discussion. In photos, the blooms appear to be nearly the same.
