Quercus hypoleucoides

Silver Leaf Oak from Arizona is a favorite tree at Xera. Tall, rounded evergreen tree with skinny but thick leaves that are sage green on top and silver white on the underside. Its handsome all the time and even prettier when the gold catkins protrude from the foliage in spring. Naturally develops a straight trunk. Fast growing tree in our climate to 35′ in 12 years. Casts dense shade but tolerates limited summer water. Extraordinarily  cold hardy. It has endured subzero readings in Eugene without injury and I even encountered one in a garden in Denver. The leaves were kind of toasted from the previous winters -17ºF(!) but it was obviously thriving. Native to the mountains of SE Arizona at very high elevations and that translates to LOVE for our climate. Exceptional leaf form and shape. Be aware that in time this tree can cast quite dense shade. Wonderful on hot summer days but also inhibiting sun loving gardening. Makes you think. Wonderfully pest and disease resistant foliage- it always looks good.
