The Quercus borealis was planted in the romantic garden of Villa Cusani Tittoni Traversi by landscape architect, Antonio Villoresi, because it offered a wonderful chromatic spectacle and the chance to observe it in autumn in all of the nuances of her crown.

This 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.
In 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.
It does not like the shade and grows well in open spaces where it can extend its branches without having potential competitors.
The 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.
In 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).
The 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).
