An oak often used in woodlands. Its crown is irregular with main branches growing horizontally. In the crown the main trunk continues to grow strongly forked. The grey bark remains smooth for a long time but later thin, dark grey bark plates appear. The young twigs are bare and glossy reddish-brown. The leaves are oval to obovate. The leaf edge has irregular and sharply serrated lobes, sometimes halfway incised (pinnate split). The leaves are 12 - 22 cm long, on young twigs up to 25 cm, and 10 - 15 cm wide. Depending on the amount of sun and the temperature the tree turns orange-red to scarlet in the autumn. Fallen leaves rot very slowly. The cylindrical flattened acorns are covered to a maximum of one quarter by the cupule: the latter is covered with small, triangular, contiguous scales. Q. rubra is a major producer of timber.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.
