Marymoor Park. If you go look at it, (and it's still there and in good shape) and decide you want one Colvos Creek nursery, Vashon Island often has it in stock. If you don't want to ferry out there you can order through the mail. Lately they've also been offering a south Seattle pickup point. Van Pelt, Champion Trees of Washington State lists the location and dimensions of the Marymoor Park bambooleaf oak. You can also find Seattle examples in Jacobson, Trees of Seattle - Second Edition.
