Quercus rugosa x castaneifolia | Stanford

This strong-growing, upright tree is a Netleaf Oak (Q. rugosa) hybrid, growing at Stanford University, near Gerona Road and Campus Drive. This tree grows in a new oak test area at Stanford, and this particular tree has far outgrown the other trees planted the same day, displaying excellent drought tolerance. Observing the leaves, it appears the paternal pollen parent is likely Chestnut Leaf Oak (Q. castaneifolia), which is quite possible, as this is a Shields Grove-sourced seedlings, and several large Chestnut Leaf Oaks grow immediately adjacent to the maternal Netleaf Oak.
