I've been slowly but surely planting lots of plants/flowers for butterflies and hummers and would love to add at least one or two passiflora vines. However, I've read that they can be quite invasive--are there any varieties that are non-invasive or at least not terribly invasive?
If you put most of them in the ground, they can become invasive. But in a pot there is no problem. Vicksburg is far enough to the south that I would probably need to put them in pots to keep them under control. Another thing is that many of them are not cold hardy, and will not survive a moderate or hard freeze if you have them in the ground. The native Maypop is an exception. But if they are in pots you can bring them into a green house, or inside near a window.
