How tall does Cezanne really get? The tag that came with it says 5-6.5 ft. So I planted it where i need it to get about 5 feet. Now I read online that some say it doesn't get over 3 feet. If that is the case I need to move it because I wont see much of it behind the stella de oras day lillies when they are mature. I just wondered if any of you in my zone 6b have it and how tall is it? Thanks so much.
