Hi I have admired the chocolate mimosa tree for a couple of years now however I read that mimosa trees can be invasive. I just saw a few chocolate mimosas the other day for sale at a local nursery. Things I read online says that mimosa trees are invasive but they don't always refer to the chocolate ones. Are the chocolate ones cinsidered to be invasive and discouraged the same way the regular mimosa trees are? I really like the chocolate look and the flowers on the tree, but I don't want to plant something that will be a problem later on.
