Quercus robur x alba is a broadleaf deciduous tree with green foliage. Attracts birds. Grows well with sun and regular - occasional water. Adapts to various soil conditions. Does well in average and well-drained soil. A good option if you're seeking something verticillium wilt resistant.
I don't know if you can grow truffles under these but they will make imposing specimens, thak a look at old white oaks and Truffle oaks and think what a bit of hybrid vigor could do.
