Passiflora ‘Adularia’. Unusual Decaloba/Xerogona interspecific hybrid. Very free flowering. Dies back at -3° C/27° F & regrows from roots. Best not treated as hardy though.
Seed from Passiflora ‘Adularia’ fruit left to rot on ground from 1999 sprouted in August 2000. Of the 50 or so seedlings that were potted up most were fairly similar, only two had some leaves with this shape.
