English oak, or summer oak, or common oak, or English oak (lat. Quercus robur)
A large, usually strongly branching tree with a huge crown and a powerful trunk. Reaches a height of 20-40 m. It can live up to 2,000 years, but usually lives 300-400 years. Growth in height stops at the age of 100-200 years; growth in thickness, although insignificant, continues throughout life.
The crown is dense, tent-like or wide-pyramidal, asymmetrical, spreading, with strong branches and a thick trunk. In young trees, the trunk is irregular, geniculate, and with age it becomes straight and cylindrical.
The leaf arrangement is alternate, at the top of the branches in the form of bunches. The leaves are oblong, oblong-obovate, narrowed downwards or heart-shaped, often with ears, obtuse or notched at the apex, pinnately lobed, large, with four to seven lobes, hard, almost leathery, dark green above, shiny, yellowish or green below, with strongly prominent lighter veins, bare on both sides, with short petioles up to 10 mm long, always falling off in winter. The blades are blunt, rounded, the notches between them are shallow.
Flowers are dioecious. Flowering begins in trees between 40 and 60 years old, along with the leaves blooming - usually in May. The plant is monoecious.
The fruit is a nut (acorn) naked, brownish-brown (1.5-3.5 cm long and 1.2-2 cm in diameter), on a long (3-8 cm) stalk. The acorn is placed in a saucer or cup-shaped bowl - plus (0.5-1 cm long). The fruits ripen in September - October.
It is moderately demanding of soil, prefers fertile, well-moistened, permeable, deep loamy and sandy loam soils. Thanks to its deep, powerful and highly branched root system, it grows satisfactorily on fairly dry and poor rocky soils. It tolerates temporary waterlogging and some soil salinity well.
