Following the nomination of the Passiflora Society International (PSI) as the International Cultivar Registration Authority (ICRA) for the genus Passiflora, formal registration of cultivars* started in 2003. The Passiflora Cultivar Registrars to date are:-
Dr John Vanderplank on the left. 2003
Dr Les King. 2003 to 2011
Dr Shawn Mattison 2014-2015.
There is no Registrar in post at present. For more information see Passiflora Society International.
The downloads below, which can also be found on the PSI site, provide a summary of the activities for the period 2003-2015; they include a number of checklists that had been produced prior to ICRA nomination, a full list of cultivars registered from 2004 - 2011 and a supplementary list of names that updates the 2003 register. Also the 1998 Wild Ridge Catalogue is included as a matter of historical interest as it lists some early hybrids by noted hybridizers Rick McCain and Patrick Worley showing correct accreditation. Wild Ridge as a seller of Passiflora closed many years ago but now Wild Ridge Organics owned by Rick and Michelle McCain trades from the same location.
*A cultivar will usually be a hybrid or, less commonly, a selected form of a species.
