Can You Plant Passionflower Near An Ac Unit?

Question

I live in Austin TX and had photinia around my ac unit that died years ago and wanted to plant passionflower in its place. I know it’s a vine and can be invasive so I wondered if you can plant it in a pot in the ground to control it? Any help or suggestions would be greatly appreciated (I was planting along my fence. A neighbor gave me starters)

Answer 1

Planting near your AC unit probably blows unwanted air on the plants. While plants do need air circulation, AC units typically put out lots of "wind" from the fan. This would be comparable to placing indoor plants near a heating/cooling air vent, which is not recommended. So make sure your plants are out of the wind zone from your AC.

You can place your starts in underground pots and that will help with underground runners. They do produce seedpods that will drop and produce plants so be sure to collect those if you do not want seedlings. If you do get unwanted seedlings, they easily pull up. Some vines, like the native trumpet vine, have to be dug up.
