Passiflora tripartita var. mollissima (formerly Passiflora mollissima) has upper leaf surfaces moderately to densely covered in short hairs, and is found in scattered NI localities, especially in Wellington, and in Marlborough and Nelson in SI. Passiflora tripartita var. azuayensis (formerly Passiflora mixta) has upper leaf surfaces hairless or almost so, and is most commonly found in Wellington, Canterbury and Otago. Both originally from tropical South America.

Related species

Passiflora tarminiana, also previously classified as Passiflora mixta, is commonest in northern NI and is similar to Passiflora tripartita, but with small, deciduous stipules, a shorter floral tube, longer petal/sepal lobes, and spindle-shaped fruit. It is also less hairy and has paler pink flowers. True Passiflora mixta is only known from the Waitakere Ranges in western Auckland and one site in Marlborough. This species has a hairy floral tube and salmon-pink flowers. Blue passion-flower (Passiflora caerulea) has five-lobed leaves, non-tubular white flowers with a ring of purple filaments, up to 9 cm across, and round yellow fruit up to 9 cm in diameter. It occurs on forest margins, scrub and hedgerows from North Auckland to coastal Otago.


Banana passion-fruit and northern banana passion-fruit are listed on the National Pest Plant Accord (see Introduction for details). Both banana passion-fruit and blue passion-flower are subject to Pest Plant Management Strategies in several regions of NZ. Details are available from individual regional councils or unitary authorities.

Derivation of botanical name

Passiflora (Lat.) = passion flower; tripartita (Lat.) = having three parts; mollissima (Lat.) = very soft; azuayensis from Azuay, a province in southern central Ecuador.
