Quercus includes trees or shrubs that can be either deciduous or evergreen. The leaves may be entire, lobed, or toothed. Flowers are not prominent, but they are succeeded by distinctive acorns. Some species may display notable autumn foliage.

Quercus rehderiana

Quercus robur is a substantial deciduous tree that can grow to heights of 20 to 40 meters. It features a broad, expansive crown supported by robust branches. The foliage consists of dark green, rounded leaves with lobed edges, which shift to a reddish-brown hue in the autumn months. In spring, it produces subtle yellow-green catkins, followed by green acorns that mature to a brown color, measuring approximately 2 to 2.5 centimeters in length. While this oak species is experiencing a decline, it remains prevalent throughout the United Kingdom, particularly in Southern and Central regions, serving as a vital source of food and habitat for various small mammals, birds, and insects.

Quercus robur 'Irtha' is a distinctive small deciduous tree that gradually grows to around 10 meters in height. Its leaves are notably smaller and somewhat contorted, creating a ribbon-like effect. These leaves cluster at the tips of the branches, and in spring, their fresh yellow-green hue resembles blooms. The actual flowers are subtle and not easily noticed, but they develop into acorns that are prominently visible among the foliage.
