noob questions on Vivax
I'm wondering what people's experiences have been with this species when kept in a colder climate. I see that it's hardy down to -5* and zone 6. I am in Columbus, Oh where it might just get down a tad bit lower than that but probably not for long and is very rare.
Will this really reach heights of 70' in this climate?
Also, do these end up really spaced out or grow closely together?
