Sorry I have never heard of this passiflora but I dough its self pollenating Most arnt sorry couldnt help more.

Doubtful. Holoscerecia has a reputation as being very difficult to root via cuttings, so if it could easily self, then that would be recommended. You could always try bud pollination, but that's an iffy proposition under the best of circumstances.

I have been informed that it is very difficult to set fruit on the Holosericea as it has a different number of chromosomes (I think it was 9). Mine is not flowering yet (it does set fruit but seedless) so if you are interested in a 'pollen swap' just let me know and lets see if we can get fertile fruit that way!
