Yes, it's quite a mouthful! We have planted many passionfruit vines over the years with mixed results. Generally we'll have a good year or two and then the vine curls up and says it's had enough.
After we lost our last one we decided to try a different variety so we bought a Passiflora Quadrangularis. Apparently it produces the largest fruit of the genus. We have got only one fruit this year but there is a late flush of flowers and they not only look beautiful they smell divine. Look forward to seeing what they produce next season.
