bra8ndy8,
I apologize. I never saw your question as I do not check on this post since I first put it up.
I have about 6 types of elephant ears, lizard's tail, aquatic mint, thalia, sensitive plant... I think that's all but there might be something else.
I would not put the thalia in if I redid it.
I will have to get in there and dig it out at some point.
These are now over 10' tall regularly and the clump continues to try and expand beyond what I want.
For height though my elephant ears now regularly get to about 7 feet tall.
