Leaves are oblong, narrow, entire to slightly toothed, bright green above with glaucous underside, up to 4" long. Catkins are gray and narrow, up to 1" long, males with red to yellow anthers. A beautiful specimen by water, but don't plant this tree anywhere near a septic system or its lines or you and the Roto-Rooter man will know each other on a first name basis. Native to Southwest U.S.
