I need some help. My parents planted a passion flower about 16 years ago. Just one. For 15 years we've been trying to kill it. I'm not even kidding. This thing has gotten so invasive my neighbors are pulling them out of their yards. I even had a roofer pull one out that had climbed up the back of a gutter and into the roof. This thing has literally taken over my entire yard. I have tried digging them up. I've tried poisoning them. We've had unusually cold winters and not only did they not die they kept thriving through the winter. Right now they are taking over my bushes down the side of my house, and they are heading for a 17 year old climbing rose I've been trying to nurse back to health for three years. I draw the line at my rose bushes. But they are also climbing and tangling around utility boxes. So they are becoming a serious problem.

How do I kill these things? They get worse every year.

I'm not seeing passion flower.

What I'm seeing...
invasive japanese honeysuckle.

really doubt the folks planted this invasive exotic...
probably planted by someone a lot further back.

What I do...
I wait for the rainy season... or after the irrigation has run or you put a sprinkler out or whatever...
It usually pulls fairly easily when the ground is moist.
Problem is... it also roots all along the growing stem, and it breaks when you pull on it...

so... just keep at it. or... get rid of the boxwoods so that you can see what you are dealing with...
after you deal with the japanese honeysuckle, plant something that helps the birds, or produces edible fruit or at least has nice flowers...

Well, some of it is passion flower, because if I don't yank it, it blooms. But by this point, it probably does have lord knows what else with it! Thanks for the info!

Not passionflower.

No, they have the big pods. They look like the second photo. I have the ones in the first photo, but they're in the wild area in the back of the yard. The vines also produce fruit.

Ok... You didn't post a picture of passionflower.

Fight that Japanese honeysuckle with every thing you have, and, you can pull the passionflower vine (where necessary), but remember that passionflower is native and an important butterfly host plant and should be encouraged.


The zebra longwing also uses passion vine as a host plant:
