I grow it in my greenhouse.

It is really aggressive in there.

I get loads of flowers, but seldom fruit.

I'm in Zone 5...GH heated to 40 in Winter.

Passion fruit is one of the easier ones to grow. It will grow very aggressively if it is not too dry and it gets enough water.

Maybe tell us where you are. Many varieties may even be able to grow outside for you, die back in the winter but later start growing up again from the roots very fast.

Thanks socal, unfortunately I have no space outdoors to grow anything, except maybe a doorstep where the neighborhood kids tend to pick apart your plants.

I had heard that it can grow aggressively and was curious how big it really gets, and if pruning it down will be problematic in terms of fruiting/blooming. I don't have a huge space for one to grow, so I'm more interested in how big they need to be in order to flower/fruit.

They are a vine, so they like to grow up against a trellis or fence.

I think it could fruit in a medium large container.

I don't really find the fruits all that great, though they do have a unique exotic tropical flavor. The vine is more desirable for its flowers.

Yeah, I'm aware. That's why I was considering growing it in a pot with a tomato cage or building a larger trellis for it to grow on. But I don't know if that would be adequate to allow it to fruit. I really enjoy, at least good, passionfruit, so I would like to get fruit from it if I can.

I should also add that I was looking at one of the self fruitful purple varieties, specifically a Nancy Garrison. Haven't decided to get one yet, but thought I'd pick others brains to see if it was worth it to replace a few non-fruiting decorative plants with the passion-fruit vine. Or if the passion fruit vine would be too much trouble grown in a pot with a trellis.

I've grown watermelon in a container next to a chain link fence and that worked quite well but it was also outdoors.

Ken, I love that idea. Seems like it would make cleaning up the vines at the end of the season a lot easier too. I've also heard of growing squash in pots along a trellis. I'm thinking I might give the passionfruit a try. I have some dried bamboo so I'll probably build a bamboo trellis into the pot and train the vine around it. I had heard that the self-fruitful varieties can be easily hand pollinated with a paintbrush, which I have done before for other plants with success. I'll post some photos when I get it and get it all potted up.

You might repost in hawaii and florida forums: many people grow them there. possibly in pots even in FL due to nematodes and poor soils..
