A columnar tree that gets a narrow oval crown when older. The tree grows to 12 to 18 m tall and 6 m wide. The branches grow straight up creating a dense crown. The young twigs are grey-brown. The old bark is green-grey and its grooves form small rectangular blocks. The leaves are obovate and distinctly larger than those on Q. robur. They are glossy dark green, turning yellowish brown in autumn. The acorns are over 2.5 cm in size. They are around half-enclosed by the cupule which is covered with triangular scales. The tree originated from a cross between Q. robur ‘Fastigiata’ and Q. bicolor. It has inherited the good characteristics of each parent species: closed columnar habit, high resistance to mildew and very wind resistant. A few years later, Q. x warei Kindred Spirit (‘Nadler’) was also selected from the same seeds.
