Quercus ×bimundorum CRIMSON SPIRE ('Crimschmidt') Quercus ×bimundorum CRIMSON SPIRE ('Crimschmidt')

Columnar oak that becomes broader when older, especially at the base of the tree, and gets a narrow, oval crown. The tree eventually grows to about 15 m tall and about 5 m wide. Originated from a cross between Q. alba and Q. robur ‘Fastigiata’. In terms of appearance, the tree has the most characteristics of Q. robur ‘Fastigiata’. The light brown bark is grooved. The leaves are shallow lobed and dark green. The underside is only hairy in the vein axils. In autumn, it turns red to purplish red, a feature that the tree inherited from Q. alba. Its high resistance to mildew also comes from its American parent. The combination of a narrow crown, healthy leaf and a beautiful autumn colour makes ’Crimschmidt’ a widely useful avenue and street tree. Was introduced to the market by J. Frank Schmidt & Son, Boring, Oregon, USA.
