Quercus dentata - Japanese Emperor Oak


  • A rarely offered, majestic tree, growing up to 25m with a trunk diameter of up to 1m. Its main value is the large, beautifully shaped, leathery, downy leaves. Quercus dentata foliage is remarkable just from the size alone; its leaves are the largest in the oak species. You will see our specimens are now paper bag brown and persist all winter. The new growth in the Spring will push off the old leaves, creating a spring clean-up chore. The thick, undulate leaf will grow to nearly a foot long and 8 inches wide at the obovate, or widest, line. The acorns mature in September to October, developing in broad, bushy-scaled cups. Requires space but it is worth to try and as all Quercus, this one works too as a bonsai or as a patio plant.
