i think its possible, but the
trees would be unlikely to thrive. and i think it would only be possible at a higher elevation, where it is colder (northern cal can be a lot colder than people think). as far as i know sugar maples are very sensitive to heat and drought, which unfortunately is what our summers are like, so it would have to be irrigated. even irrigated our hot summers might do them in, this is a much hotter than anywhere they grow naturally.
as others said, we do have abundant amounts of the big leaf maples, which are really very prolific here and thrive without any human intervention. the big leaf maples are everywhere here, one of the most common trees around in the mountains.
i have never seen anyone plant a sugar maple anywhere out here, but i have seen some people plant the red maples for landscaping trees, although these are much less picky about temperature and
water.
another note- people do tap the big leaf maples for syrup.
