Quercus x macdanielii ‘Clemons’ – Heritage® Oak Tree

Botanical Name: Quercus x macdanielii ‘Clemons’

Alternate Name: Heritage® English Oak, Truffle Oak, Quercus macrocarpa x robur

The Heritage® Oak tree (Quercus x macdanielii ‘Clemons’) is a relatively new hybrid resulting from the cross between the English Oak (Quercus robur) and the Bur Oak (Quercus macrocarpa). It is a stately and tough, large sized specimen tree with a graceful, broadly pyramidal form.

The Heritage® Oak tree has a reliable upward growth habit and strong central leader, with branching down low on the trunk. This oak is long-lived and can endure to an age of 300 years – giving it the name of Heritage® Oak. It grows to a height of 60-80 feet tall with a spread of 40-50 feet.

The flowers of this oak are catkins. They are greenish-yellow in color and emerge in the spring as separate male and female flowers, just as the leaves are emerging. The fruits are acorns that can cause a mess when the tree matures and produces a big crop, but they are very attractive to birds and small mammals.

The leaves are lobed and a glossy dark green. In the fall, they turn a pretty yellow color.

The Heritage® Oak tree is very adaptable to different soil types and pH, as well as various environmental conditions. It tolerates urban pollution and both dry and wet locations. This oak is also resistant to powdery mildew.
