@NorCalCherylLyn I'd guess it's a chestnut oak. Might be good to plant it this fall, after the heat of summer, but before the hard cold sets in. Though as long as the soil isn't frozen it'll do fine. Oaks like to put their taproot down when young. And they do grow pretty fast during the first ten years before they slow down a bit. It helps them to recover quicker if/when the deer nibble on them, or rub antlers on them. Dang deer.
