Passionflowers are so similar to Wisteria. Both of them are beautiful. But neither of them are really wanted in your yard unless you have a way to control their runners for sure.

Now that you have the plant (and runners), you could just, as the previous comment stated, cut the runners down to the ground. But the roots are still there, waiting to take over your flower bed. While I hate to suggest it, the only real way to get rid of the runners is to kill the mother plant.

I would recommend using Roundup (a lot of it) and hopefully letting the poison seep to the runners through the root system.

If you want to keep the mother plant... Don't. Just don't. Unless you save some of it to grow a new one or buy more seeds, the way your first plant is planted won't work. You have to put the plant in a rather large pot in the ground to contain the root system. Now, I've only heard of this being done, so if you want to keep the passionflower, do your own research!

I hope this helps! Don't let the passionflower take over the world!

You're so lucky. I was just about to plant passionvine in my azaleas so the beautiful passionflowers will run along the tops of the bushes bc i don have a fence line. I googled this to be sure the passion vine wouldnt kill the azaleas w it's intrusiveness:)

Planting it in a large pot won't be able to control its root. I learned my lesson a couple of years ago. I planted mine in a huge pot. After one season, my next door neighbor discovered a strange looking plant/vine coming out of her lawn. She pulled it and traced it back to my side of fence. I tried to move the pot to figure out what was going on, and found a thick snake like root sneaking out via the hole at the bottom of the pot. That's the source of the passion flower plant in my neighbor's yard. By the way, I did place a big piece of rock inside the pot to semi cover that hole, but the sneaky root obviously found a way to get out anyway.

You could let your vines "drink" RU from a jar. This eliminates spraying copious amounts or risking getting it on other plants.

If trying something similar in the future, put the pot on a patio or raised on a stand, so the roots can't escape the pot. Covering the drain hole would be more likely to kill the plant than contain it, if it fills up with water during a rain.

I asked a UNC professor about planting tomatoes in the same area the second year; how do you prevent disease? He said if I planted the tomato in a pot -- placed on blocks-- the roots would stay within the pot because they die when they hit air. That might work for the passion flower.

In what zone will they died in winter and act as an annual instead of a perennial?

I found this article while searching to see if I could plant passion flowers and azaleas next to each other. I was quite shocked at all the recommendations to use Round Up! Do ya’ll seriously think round up only poisons your plants and nothing else?! I get that people want to control their gardens, but seriously, find another way. That stuff is bad news!

I checked with a friend in San Diego to see if he has had any trouble. He is growing "Passion Flower Frederick" for years and he said it is NOT invasive..I think it is Passion Flower Incarnata that takes over the place.

With weeds/plants like that.(underground runners..like Canadian thistle/Wisteria..which I am fighting) .2-4-d in the spring and then round Up in the fall..If sprayed judiciously and carefully it doesn't cause harm to anything else.
