ponytail plants

Question

I live in Victoria, Australia. My ponytail trees grow outside where we have heavy frost and one tree shares a rose garden bed. I was wondering how big will they grow? Maybe I will have to move the roses, as I know the roots will be big and dense on the ponytail. Thank you

Answer 1

A Ponytail Palm, though slow growing, can reach 30 feet tall.
