Fast-growing tree that can grow to approx. 18 m high and 12 m wide, with a broad, vase-shaped, semi-open crown. The trunk is usually branched low down with several sturdy main branches slanting upwards. As the tree ages, the crown broadens. The grey trunk is smooth at first with pink to brownish orange lenticels. Later, it flakes off in sheets, revealing the orange-brown bast underneath. The ovoid to elongated leaves are soft green and turn a bronzy red and orange-yellow in the autumn. The top is long and tapers to a point and the leaf edge has single teeth tapering to a point. Because 'Flekova' has a narrower manner of growth than the species does, this tree is better suited for use as an avenue tree. Unsusceptible to Dutch elm's disease.
