Quercus imbricaria


Shingle Oak




Origin:  Central and eastern United States of America.
            Mike's Opinion

"

An excellent and somewhat unusual tree because of its uncharacteristic oak leaves that are retained 'en masse' for most of the winter months. It is usually problem free but does need room to grow since the branching habit is almost horizontal to the trunk. I have found that it has done well for me on moist, mulched, heavy clay soils.
