Stanford has avocado trees in the quad, IIRC. Redwood City should work just as well. I need to get my hands on the Gem variety due to 100+ extended summer heat in my neck of the woods. Even then, the leaves might burn without a larger shade tree nearby.
GEM isn't worth growing -- it's not that good of a fruit. Hass does just fine even in high heat. Just plant the tree in a spot that gets some afternoon shade.
