Quercus ×hickelii is a hybrid, created from a cross between Q. pontica and Q. robur. The tree is most similar to Q. pontica, but grows stronger, has slightly thinner branches, smaller leaf buds and smaller leaves. Q. ×hickelii forms a tree 8-15 m tall with a round crown. Branching usually starts already at a low height above ground level. The young twigs are reddish-brown, the older bark is brownish-grey, smooth to finely grooved. The inverted ovoid leaves have toothed leaf margins, with the tips of the teeth rounded. The leaves are a glossy dark green, turning brownish yellow to dark yellow before falling off in autumn. The leaves are on average about 5 cm smaller than in Q. pontica. The acorns are also slightly smaller than in Q. pontica. They are about a quarter surrounded by the nap, which is covered with felty scales.
Because Q. ×hickelii grows more vigorously than Q. pontica, it is more suitable as a tree. In terms of ornamental value, Q. pontica is slightly nicer though. Q ×hickelii grows best in fertile moist and loamy soils. The tree is sensitive to prolonged drought.
