Quercus castaneifolia

One of the fastest growing and truly most magnificent of all oaks; one only needs to visit Kew to see this! My collection from the Caspian Hyrcanian forests, very near Lankaran, S. Azerbaijan. A superb specimen for a large garden or parkland forming a huge rounded crown. The leaves are rather chestnut-like, funnily enough, margined with coarse, triangular teeth.
