How quickly will the vines grow? There were a few at the greenhouse I went to with a couple of vines already about 12" long but was hoping to be able to fill out the cage relatively quick. I'll have plenty of fake leaves and vines for the veiled as well but wanted to make sure he also had a nice full natural cage too.Just one? Pothos. Simple, safe, hard to kill and branches grow as vines that can be draped throughout the enclosure and will support a veiled. My original pothos from more than 10 years ago has been divided and is now about 15 plants.
