<\/span>More<\/div>\nThis North American oak belonging to the beech family has, in fact, a large domed crown with straight branches. The leaves are alternate and dull green in colour and divided into about eleven lobes with indentations that extend to the centre of the leaves which have short, sturdy stems. In the autumn, they turn orange, dark red or brown.
\nIn America these trees are prone to the attack of a particular fungus that is spread by bark beetles. The onset of the disease is marked by a brown colouration on the leaves. So that imported oaks would not be carriers of this disease, the wood is subjected to decortications of the bark, and fumigation.
\nIt does not like the shade and grows well in open spaces where it can extend its branches without having potential competitors.
\nThe fruits are called acorns borne in cup-like structures called cupules, similar to bowls. These are located at the ends of the branches and mature in its second year. These trees are very prolific, and in the fall when the fruits fall to the ground, they create a carpet that creaks whenever animals and men pass.
\nIn the park of Villa Cusani Tittoni Traversi, these exotic species can be seen close to the play area where the trees grow and mature alongside different varieties of native oaks like the downy oak (Quercus pubescens) and sessile\/Cornish\/durmast oak (Quercus petraea).
\nThe plant is valued for its rapid growth, so it is widely spread in the gardens of country villas in Lombardy and in the parks and woods of Brianza. Inside the Oak Forest of Seveso, for example, you can admire splendid examples of Quercus borealis next to the equally ornamental and exotic scarlet oak (Quercus coccinea).<\/p>\n<\/div><\/div>\n<\/div>\n
