Vines scare me. Let’s face it: they are high-maintenance, hyperactive stranglers just waiting to invade your siding or your neighbor’s yard. But I love them just the same.
A few years ago, I was browsing at Bramble Wood Nursery, one of my favorite vendors at the State Farmer’s Market, and spotted passiflora incarnata “Incense.” It was not on my shopping list, and I had nowhere to put it. But the lone flower in bloom on that deceptively small plant was so striking that I gave in. For years I kept it confined to a pot, afraid of what might happen if I planted it in the ground. Now it’s free, and it’s making me nervous.
Passiflora incarnata, commonly known as passion flower vine or Maypop, is hard to resist. It looks like it should be a tropical, but it’s hardy from zones 6 - 9. Its huge, crazy flowers resemble a purple sea anemone and are a nice change of pace from clematis. It’s a host plant for the Gulf Fritillary, one of those pretty orange and black butterflies that aren’t Monarchs or Painted Ladies. Since it doesn’t really get going until August, it gives the garden some interest - and the bees and butterflies something to eat - after the big floral display of the summer. The shriveled flowers yield passion fruit. And it’s native.
Of course, being native doesn’t mean you can’t be a pain in the neck. On internet garden forums, people from Florida and Texas write that they rue the day they planted it, then issue dire warnings about what will happen to you if you make the same mistake. On the other hand, gardeners in North Carolina and more northern regions call it aggressive but not invasive. I’m inclined to agree, as each year I see one and only one growing wild in an open, uncultivated area in my neighborhood. Furthermore, it is not included on the North Carolina Botanical Garden’s list of invasive species, and responsible local nurseries such as Bramble Wood and Niche Gardens sell the plant with no warnings.
Still, I’m a worrier, which is why I grew mine in a pot for several years before finally letting it loose this spring. It was a bit slow getting started, and for a while I wondered if the three trellises I had lined up to support it had been overkill. On the contrary. By mid-August, it had entirely engulfed the trellises, draped itself over the dwarf crepe myrtles, latched onto the callicarpa, and was in the process of grabbing the winterberry holly before I put an end to its aspirations of world domination and cut it back a bit. Its exuberance is nerve-racking.
Do I regret my decision to set it free? Not yet. It looks far better than it did when its roots were jammed into a pot. But ask me again next year, when I’m on permanent sucker patrol. With passiflora incarnata, the price of liberty is eternal vigilance.

You're hilarious. And incredibly knowledgeable.

You are too kind. Plus you are related, and therefore, biased. But thank you anyway!

sucker patrol will need to be at least 30 feet in diameter, but put it where you can mow around it and no problem! I did not do this !!! worth it though, love watching the bumble bees and the hummers go nuts over it!!!

Funny you should mention that. I started seeing suckers in September - way ahead of schedule. , too, ran over them with a lawn mower. So far, so good.

Hi Aaron! I regret to report that I have no update - the passiflora incarnata was at my previous house, and I haven't seen it in 2 years. Given who bought the house, I am going to guess that it has taken over the entire yard by now. They strike me as he non--interventionist types. The garden in my current house is way to small for anything like a passion flower vine. As for my blog, my job ate it, so it's on hiatus. Very sad. Hope your garden is flourishing.
