Comments / Commentaires

This high-altitude oak is a beautiful ornamental tree. The narrow evergreen leaves with the occasional asymmetric lobe to add interest are white underneath; the plants have grown vigorously, and the young growth is purple.

It suffered drought damage at La Bergerette in 2022, even though it is found in nature in the dry southwestern states of the USA. If there is rain in this area, it falls largely in summer from enormous thunderstorms. Quercus hypoleucoides shows adaptation to this - the acorns are already ripe by the summer, ready to germinate immediately after rain with rapid root extension to follow the moisture downwards as it recedes in the soil. A solitary specimen of the latter on the parched plateau produces acorns at La Bergerette; but in a less dry area on the slopes a group of three have never produced an acorn between them.
