I collected the acorns of this tree near Lake Isabella, CA in the southern Sierra Nevada. It was a particularly handsome form of what can be a less than majestic species. Densely foliaged with a straight upright trunk about 25′ tall with a rounded crown. Wow. We hope the progeny are as cool. Interior Live Oak of California. Evergreen tree to 25′-35′ tall with a spreading crown. Was native in Oregon in the past as hybrids known as Mohr Oaks (Quercus kelloggii x Quercus wislezenii) still can be found. Hardy to short shots to 0ºF. Grows about 2′-3′ a year in youth. Water to establish the first year then none in subsequent years.
