Quercus engelmanii | Stanford

Moving north in California, nearly 400 miles north of historical Engelman Oak habitat is his is a young Engelman Oak growing in the Stanford Arboretum, looking remarkably similar to the tree in the preceding entry. Interestingly, The acorn from which this Engelman Oak was grown was the Shields Oak Grove in Davis, and this tree shows evidence of hybridization with Q. castaneifolia. Tree in photo is ten years from planting as a seedling, and received supplemental irrigation for the first two of those years.
