I'd never plant it again. At my old house (OKC) it was coming up all over the yard in the grass from the roots and it got wider every year until the whole yard was infested. Vines would shoot up every few feet, we'd mow the grass then there'd be new growth sticking up in a couple days because it grew so fast and it looked awful. Some people like them for the butterflies but frankly something that aggressive was ugly, not worth it. I like butterflies as much as the next guy but there are better choices if you have an urban yard.

Well, they do have a reputation for runners (as TR said). I grew caerulea (the non-native blue and white one) and it proved evergreen through at least one Chelsea, OK winter. Unfortunately I only had it two years, due to me moving...so I can't give a long term report.

The native incarnata, is not invasive by definition, being native, however, it does spread by runners. I don't see it going ape on the fencerows, but I've never tried it in a garden/yard.

I have Incense (a hybrid involving incarnata) planted in my yard in Arkansas now, and I may regret it but I intentionally planted where I can mow to control. I loved the flowers facing my brick entry way last year....I will have to see were it pops up in a few weeks.

I also have a caerulea hybrid, Clear Sky, on order that I plan to plant in about two weeks..but it's new to me, so I can't say anything about it.

I think it's a matter of planting it where you are certain you can control and eradicate it, if necessary. Don't plant where you can't. I'm told vines like this make bad neighbors (and make neighbors mad), so keep it on your property.

As a final caution, I know of a nursery that assigns the common name 'Vine that ate the greenhouse', to P. caerulea. However, that vigor is great when you're talking tropical and subtropical plants that need the vigor to be hardy in our temperatures.

Thank you! I'll not be planting this!!

Well that's up to you...the flowers are quite exotic and the vines are umm vigorous (lol), and flower a lot when established. They're planted a lot farther south (esp Florida and California).

Obviously, I found it worth trying....and I liked it. But like I say, I'm a relative newbie at Passiflora, so I could still be naive.

Sorie, I grow it without any trouble. I have grown p. incarnata, which is the traditional "maypop" vines. THAT was was a little rambunctious, but I was able to pull in out without too much trouble.

P. caerulea doesn't give me as much trouble. This winter it stayed green, so I should have good vines this year, but last year they got knocked back, all the way to the ground and I didn't have much of a show. They are growing behind a rose bush, and they do take over the rose bush, but that's fine. I have posted pics here several times. I'll see if I can pull them up.

P. caerulea thread (2012)

I remember that thread (now that you show it to us).

Thank you Lisa. that is beautiful!!

So is Incense, I don't have a overall view, just a bloom closeup.

Sorie, I am in OKC, and if you read the thread, you can tell that not every p. caerulea is as successful as mine. I don't have a single clue why mine does so well. It's out in the open, no special mulching. I have a better vine if the winter hasn't been as harsh and the leaves live through the winter. I see that photo is dated for the end of April. Oh, yeah, bring on April :)

If I had a good place for the p.incarnata, I would grow that too. I ought to grow one where it could grow into my neighbor's tree :)

I had one for a few years and so did my neighbor, but I think they both may be gone now. I think they are beautiful and mine didn't spread at all.

I grew one years ago, it got very larger but it didnot spread. It went through some very tough winters and cme out fine. Think I'll try one again.

Yaaay! I got a UPS notice yesterday...tomorrow I'll have my passiflora
caerulea hybrid (Clear Sky). Also two unusual herbaceous clematis to
plant...
