P. antioquiensis x P. tripartita var. mollissima, though this is sometimes disputed. There are a number of different crosses called Passiflora x exoniensis, in the same way that there are a number of different P. alata x P. caerulea hybrids called P. x belotii. My own opinion is that the plant pictured here is correct & that some of the others are different versions of the same cross or P. antioquiensis x P. tarminiana hybrids which are similar but hairless with lighter green & possibly narrower leaf lobes.

P. x exoniensis is also often confused with & labelled as P. antioquiensis, they can be distinguished however when they flower. P. antioquiensis flowers are smaller & less showy, with the same petal colour inside & out & are produced on peduncles of 2' to 3' long. P. x exoniensis peduncles may be at maximum up to a foot with the inside of the flower being a fluorescent pink. The one pictured is probably the best of them with large leaves & stunning spectacular large flowers. It does not produce any pollen as far as I can tell, but will set fruit with pollen from other Tacsonia. It is planted in a sheltered spot so it does not get full sun all day - as like its parent P. antioquiensis it does not like too much heat. It is shy flowering in summer.
