Quercus hypoleucoides | Coastal Southern California
Adding to the visual appeal of Silverleaf Oak is the reddish-colored new growth, seen here. The hooked lobes visible on the green leaves are less-than-typical for Silverleaf Oak, but may be a juvenile trait associated with this sapling tree. Leaf shape can definitely vary from the time a tree is young until it becomes more mature. The hooked lobes are also typical to Quercus sartorii, a Mexican oak species in the same oak subgenus as Silverleaf Oak. It's also in the same subgenus as a variety of California native oaks, including Q. agrifolia. This could be a very interesting and widely adaptable hybrid.
