I've found you can slow these guys down a bit by limiting water and not feeding. I overwinter mine in a pot. The first picture was taken May 15th. The 2nd picture was taken today, July 5th. Some of the leaves are taller than the pot! I've been watering and feeding the bajeebers out of it since I put it out.
On another note, I've also discovered that pretty much all plants prefer under potting to over potting ... especially when they small.
