I think the passion flower would eventually (quickly?) bully the rose to death. At least in my climate, passionflower vines are evergreen,too, which I don't think would be good for the rose , either.

Thanks, Bart Bart. I don’t think it is an evergreen in 7b but still. I had wanted this plant for years and now i fear i will neeed to get rid of it.

I don't have your rose but I do have some climbers and several are substantial I don't know what kind of passionflower you have, either. Is it the native variety? I grow that kind. Or, rather, that kind grows without any help from me in the woods. I don't think I have a rose that could stand up to any of them. I like passionflowers but not in my garden. You are in PA, though. Maybe it's more mannerly for you.

If I were you I'd be careful with mixing passiflora with roses --- I think the passiflora is likely to be much more vigorous and, as suggested above, it is likely to overwhelm the rose. This is especially true if you are growing incarnata or caerulea. Watch out with those two because they will spread via runners and they can take over your garden if you aren't careful. Maybe some of the cold hardy hybrids would work better for you.

K S, the vine is in a large pot. oh well.

It’s also an Iridescence. Don’t know if that makes a difference. I got it via mail order and it was a puny stem. I’m stunned by it’s growth.

Wow...I had no idea passiflora were invasive!

Not all passiflora is invasive. Some are very mannerly.

I would not put my passion vine with roses because if I need to spray I would not want to kill the caterpillars on the passion vine. It is a host plant (not the red variety) for Zebra Longwings, Gulf Fritilary, and Julia butterflies... probably more but they would need to be in the brushfoot family. I have so many caterpillars that the passion vine would never overtake my roses.... but I do have to spray for chili thrips and would not want to hurt the caterpillars.

Also, here in South Florida I need to have good airflow around roses to keep fungus at bay. Passion vine would defeat the purpose.

You might actually be OK pairing it with the rose if the passion vine is in a pot (which might keep it stunted), and I haven't grown Iridescence myself, but it is a hybrid so less likely to go completely feral on you. You can always try it out and move it if it looks like the rose is suffering. :)

Not only will it take over it will spread all over you garden....beware!!! Hang a picture of the plant in your garden and don't plant the passion vine....

Passion flowers are wonderful, and can host some beautiful species of butterflies. I don't know that fritillaries would be that far north, however -- I think it's range is spotty north of coastal VA. Tropical and subtropical Zebra longwings definitely won't venture that far.

If you are growing the hardy species of passiflora I imagine, it can be fairly rampant. I would expect top kill in zn 7, but when it returns, it will likely "pup" all around, if you release it.

I have Iridescence with Mutabilis here.

Sheila - it seems so strange to see such an interesting plant growing in a yard and not in a jungle. :) I absolutely LOVE how the bees love the passiflora!!

I agree, Carol, the passiflora is really out of this world.
