This new introduction from J. Frank Schmidt Nursery in Oregon is a great densely branched Maple. It has less co-dominant leaders, but still a bright red fall color. With better resistance to spider mites, and it’s fast growing nature, it is a great tree.

With its silvery underside blowing in the wind, this deciduous tree makes for a very pretty landscape accent. It will get very large however, so may be more suitable for a lawn tree.
Dark, glossy leaves, that hold their orange color well into fall. Great drought resistant cultivar.
Dense foliage with heavily textured dark green leaves that have very distinct veins. Steel-gray bark is showy in winter. Tolerates a range of soil conditions and air pollution. Can be pruned into a hedge shape, trees in a line can be pruned into a hedgerow which is common in Europe.
