I know of a 20’ tree in a private garden in the suburbs of Salt Lake City, Utah (zone 7b). It stays perfectly evergreen all year round, and has never seemed to have any damage whatsoever for the many years it’s been there. I’ve read many places this tree is hardy to more like zone 6b or 7a, it’s natural range spans a pretty big area but it does colonize in some higher altitude mountainous regions of Arizona. These areas get snow every winter and can get some really cold temperatures on occasion (around 0 F). This is by far one of the most beautiful evergreen oaks there is, and it is definitely hardy here in Utah long term. |
