English oak (Quercus robur)
Description
“Pet poisonous” – Toxic parts: shoots, leaves Quercus robur, commonly known as common oak, pedunculate oak, European oak or English oak, is a species of flowering plant in the beech and oak family, Fagaceae. It is native to most of Europe west of the Caucasus. The tree is widely cultivated in temperate regions and has escaped into the wild in scattered parts of China and North America. Quercus robur is a large deciduous tree, with circumference of grand oaks from 4 m (13 ft) to exceptional 12 m (39 ft).[citation needed] The Majesty Oak with a circumference of 12.2 m (40 ft) is the thickest tree in Great Britain,[citation needed] and the Kaive Oak in Latvia with a circumference of 10.2 m (33 ft) is the thickest tree in Northern Europe.[citation needed] Quercus robur has lobed and nearly sessile (very short-stalked) leaves 7-14 cm (2.8-5.5 in) long. Flowering takes place in mid spring, and their fruit, called acorns, ripen by the following autumn. The acorns are 2-2.5 cm (0.79-0.98 in) long, pedunculate (having a peduncle or acorn-stalk, 3-7 cm (1.2-2.8 in) long) with one to four acorns on each peduncle.
