Nuisance plant in Hawaii, maybe that is why. Search "california noxious weeds", see if anything comes up.

if you want passiflora incarnata (sp?) you can find it in just about any overgrown field or waste lot in your area. you can just dig up a live plant because it grows as a weed and the birs spread its seeds far-and-wide.

I think I saw them available through Richter's if you don't find one here. I've read they are hardy but I am skeptical. I get the feeling that if they survive winter they either won't flower or the fruit won't ripen.

I live in California and don't really know if there's a nursery or garden store that sells that variety in Hawaii. :( But, If you can get your hands on some cuttings, I would deeply suggest that you try to root some. I have seen many 'Frederick' passies being grow from cuttings at my local city college. (They have two mature vines) Since that spiecies is a hybrid, you need to propagate them either from cuttings or graft in order to get exactally what you want... (seed grown plants will be unpredictable) Although, I have grown a few from seed myself before knowing of this information. I don't really care which parent side ends up being more dominant just as long as they produce gorgeous flowers and edible fruit, that would be good enough for me. ;) Hope this is of any help, Daniel
