This cultivar grafted on seedling can be controlled to the relatively small height of 40' tall and 18" diameter base in ten years. Over a ten year period it is a good (not excellent) performer in zone 10b, struggles in zone 9b, and dead in zone 9a.
Keep in mind that zones are determined by 10 year averages.
