Green Anole ReptiBreeze Tree

I have a medium size ReptiBreeze (16W x 16L x 30H Inches) that I plan to use as a basking terrarium for 3 green anoles. Obviously I could just setup sticks. I am wondering if anyone knows of any trees (preferred) or plants that I could grow in a pot in the ReptiBreeze that have strong enough branches for the anoles and will not outgrow the reptibreeze? (It's okay if it's a tree/plant that I have to trim the branches/top of every so often to keep it contained)

I have always used pothos with anoles. It is a vine that grows fairly quickly, so you could use sticks as perches and grow the pothos around the sticks. As it grows you can wind it around in any way so that it will not outgrow the enclosure, and you can also trim it.
