Closest Variety and Key Differences
Passiflora ‘Snow Queen’PVR is a stunning, hardy, pure white hybrid which is a great improvement on the ever popular P. ‘Constance Eliott’, which has smaller flowers and is more prone to virus problems. As well as greater flower size, the leaves and petiole glands as above are distinctive and can be used to differentiate Snow Queen from other white flowered Passiflora hybrids.
