Aristolochia, but which one?

Elegans, Gigantea or yet another one? thanks for your help

Gigantea! Cool conversational piece. Here are mine.

I'm glad to know the real name of this one, I thought mine was grandiflora, but I see after looking that one up, it has a point on the end of it, and this one doesn't, so I have the gigantea too.

thanks Lily,

Cathy, I purchased a dozen of these last year. 2 in a protected spot came back, but they haven't set flower yet. The one I've is a new one that still sit in pot. I was wondering if this particular vine like it pot bound. Any how, the 1st bloom started in June, this is my second flush of flowers.

I'm not really sure Lily.

I've got one in the greenhouse in a pot, growing up a trellis, and it has rooted through the pot now and is about 20 feet long and 5 feet wide, up inthe rafters and everywhere. And we cut this thing back to 2 foot last fall.

I have 2 more growing up a trellis in the front yard. and one is 4 times bigger than the other even though they were planted at the same time, no blooms on that one though, and not many on the one in the greenhouse, I suspect that's because it's not in the sun.

I really don't know if they like it root bound, I would think they'd grow bigger and better out of the pot in the ground. but since mine has gone through the bottom of the pot, it's considered in the ground now LOL

Kathy, I'm uncertain of what's it really needs. The one came back for me, it's partially shaded by my clematis and Roses. But it did bloom last year. I think it may be half hardy, the small microclimate where I planted this particular one perhaps got sheltered thus safe from frost, and it's out of north wind. My second survival vine in the back was much too shady (on north side of the house). Thus just marginally growing and not making any bloom, ever.

I have had the same question on mine. I have four, two have blotched leaves and the other two have solid leaves. The solid leaf ones have started to bloom but I was not sure which was which.
I think that the one that is blooming is Gigantea I think I"ll have to bring in this winter. By next winter I may be ready to let it do its own thing.
I have another one that has the real small flowers, maybe an inch long. Not sure the name of that one either. All summer it is covered with eggs or cats.

Betty,
I think the small one maybe Elegans, it's a specie thus will produce viable seeds. Yooohooo, I've one too (come to think of it, I haven't planted that one either. Still in a pot). There, you're right. We do like those unsual exotic looking vines.

I've got a few other varieties, if I had my camera I'd take photos, one is about to bloom, it's a ground cover, that is variegated, and I forget the other two's names.

Whaa whoo...look at your with those unique blooms, Vossner...awesome...all the pics!!!

Hello, I'm NEW to this forum, but I have some of these too...I love them. And they are beautiful!

Someone sent me seeds a few years ago and I just got around to planting them. I have 4 growing in 3 gal pots with a circular tomato cage for support. They haven't bloomed and the package was marked Dutchman's Pipe Vine but nothing else. I had one a few years ago that was decimated by cats and never came back but the leaves were huge compared to this one. I will have to wait to see if I get blooms and then maybe someone can ID it.
