If you dont want the passiflora to get away from you, id suggest that you put it in a large container on cement,stone or even plastic so it doesnt send its roots out the water holes of it's container and into the ground. passiflora is a beautiful vine it has enchanting exotic looking flowers and some having fruit thats edible. you just have to decide if you put it in the ground which might be harder later should you decide you want to move it from where its at or you can keep it in a container under your management
