The batches of Australian passionfruits I got from various U.S. based vendors were all duds -- while most germinated, they were strange P. edulis plants (they had red stems, which was weird for P. edulis) and didn't ever flower or fruit, even in a greenhouse.
i have an Edulis, about 4yrs old with red stems.
i get a few flowers here and there, no fruit.
pretty sure i bought it as "Purple possum", maybe they grew it from seed ?
glad to know they can graft, i might keep the root which is larger than my wrist now.
i just grew another edulis too. 1 1/2 yrs last fall, had tons of flowers, no fruit.
ive grown Maypop (Incarnata) 4 times from seed... , got fruit every single time.
once, the vine was only 5ft tall in a 3gal pot, produced 1 very tasty fruit.
Maypop is also more cold hardy than edulis... it is vigorous, and can sucker though.
Maypop grows wild on the gulf coast. (i think a type of bananna passi does to)
and i think that is a trick to make them flower/fruit is to constrict the roots.
i would use a 7 to 15gal container.
I have 2 maypop growing from seed now... still kinda small for cuttings
but PM me in a month or 2 , i will propagate 4 or 5 just in case.
I did get a batch of Australian seed from a forum member that is doing well and just flowered for the first time, so we'll see how that does.
None of the banana passionfruits of other types I've had are worthwhile.
let us know about the Aussie types
the hot climate might be a better match of me in South Louisiana
i just bought bananna passi seeds
is the fruit that bad ? ive read it was good, just not as good as flavicarpa, ligularis.
here my edulis / possum purple (red stems - no fruit)
Maypop vine + flowers.
