I now have (in my house) about 2 dozen types that are over 4 foot tall. I will be looking to add more varieties when it gets warm out (and I think it is safe to ship plants.) A search on Dave's and using Google did not yield much. Many are ID'd as grows tall and I am not sure I trust all sellers to describe correctly the plant they want to sell. Can someone provide a list of Sans. that do grow tall - let's say over 4' ? And/or a good link?
