Scarlet Letter™ Oak

Botanical Name: Quercus robur x alba ‘Scarlet Letter’

The Scarlet Letter Oak tree is a striking and unusual newly improved variety of oak, similar to ‘Crimson Spire’. This tree is a hybrid of Quercus alba and Quercus robur.

Quercus robur x alba ‘Scarlet Letter’ has strong branches and a dense, compact growth habit that can withstand the weight of snow and strong winds. It has an upright growing, columnar shaped crown. It is a very useful addition to landscapes as a screen between properties or a vertical accent in a garden. It is also very effective when planted in a row, lining a driveway. The Scarlet Letter Oak tree grows to a height of 35-45 feet tall with a spread of 10-15 feet. 

The leaves are an attractive mid green and deeply lobed. The fall color is a vibrant red, and this tree will hold onto its leaves long into winter.

The Scarlet Letter Oak tolerates a wide range of conditions, adapting well to most types of soil. It is also drought tolerant and withstands summer heat remarkably well. Fertilize with iron and amend the soil with organic matter to encourage strong growth and good fall color.

This oak has excellent resistance to leaf scorch and powdery mildew and moderate resistance to leaf spot and root rot.
