@Tomas: Interesting - so cuttings retain their maturity, then? Nice to know; whenever I have to prune it back I can make a bunch of babies that don't take long to fruit.
Heh, planting outside isn't an option for me. That would otherwise be known as "purposely killing my passionfruit"
A cold snap can drop temperatures below freezing in even september here. And you know how some tropicals can stop growing if temps go below 10C or even start to die back (for example, I know that coffee does that)? Half our nights even in July get that cold! And our average July day gets up to only 15-16C! (~60F, for those of you in the US). Our winters aren't super-cold by American standards, but we basically have no summer.
@Fyliu: Indeed, I posted the top picture for comparison. I've been getting shoots like the top one for a long time; they grow into vines. But the bottom type I don't think I've seen before. I did some google image searching of passionfruit buds, and I think it is a flower. Yeay!
@stressbaby: The concept of root pruning has always scared me, but then again, I've heard it can be good for a plant. So I'll probably give it a try in a few months when it inevitably fills up the 15 gallon.
@fruitlovers: I already moved it into a 15 gallon, heh; I'll just deal with having a very large passionfruit vine and probably end up giving a bunch of fruit away. Or hmm, wonder if I could sell it here. Icelandic-grown passionfruit on a commercial market, I bet that'd be a first. Does passionfruit fruit in flushes or continuously? No worries about it growing into the ground; the ground is a solid floor and there's an undirskál (in English, what do you call that thing you put under a pot?) between it.
