The flowers of the English Oak are small and inconspicuous, appearing in long, slender catkins. The male catkins, known as aments, dangle from the branches and release pollen during the spring. Female flowers, found on the same tree, are smaller and less noticeable. The flowers lack the showy and vibrant characteristics of some flowering trees, as oaks are primarily wind-pollinated. The subtle, greenish-brown hue of the catkins blends in with the emerging foliage, contributing to the understated yet essential reproductive phase of this iconic tree.
Fruit:
Acorns (see images). The acorns grow up to 2.5cm long in size. Their stalks grow up to 2 inches long and are probably the best way to distinguish this tree from Sessile Oak. Sessile Oak acorns are not stalked. Each acorn sits inside a cup on the end of a long stalk.
Leaves:
A deciduous, long-lived tree with unstalked, dark green, lobed leaves. The very similar-looking Sessile Oak has stalked leaves. The leaves of the English Oak turn yellow in autumn.
Aroma:
The aroma of the English Oak is characterized by a subtle blend of earthy, woody notes with a hint of sweet mossiness. As one approaches an English Oak, particularly in warm weather, the scent can be mildly aromatic, providing a natural and refreshing fragrance.
