Quercus rubra
Northern red oak

- Family: Fagaceae
- Origen: native to the eastern half of North America
- Interesting fact: although the wood is resistant, it does not last long and is used primarily to make furniture. The bark contains a lot of tannin and is used to tan hides

A deciduous tree that can reach some 35 metres in height, with silvery-grey bark
that cracks.

The leaves, up to 20 centimetres long, are dull on both sides, light yellow in colour when they sprout, and then green and reddish when autumn arrives. They are deeply lobed and very polymorphic. The lobes are very pointy. The petiole measures some 2.5 centimetres long.

The flowers appear in mid-spring. The females are located at the axils of the young leaves.

The fruits are acorns 1.8-2.5 centimetres long, with a 1-centimetre peduncle and a shallow cupule. They take two years to ripen and fall in early autumn.
