This photo shows foliage of a young Monterey Oak (Q. polymorpha) growing at Stanford. Monterey Oak is semi-evergreen, and here it is seen transitioning between winter and spring, with lovely pink red new growth. Monterey Oak has performed adequately at several locations at Stanford over the last decade, but not well enough to recommend widespread use. Monterey Oak grows in a fairly wet part of northern Mexico, and wants a bit more moisture than most of California can provide for best growth. In the Bay Area climate, which is quite a bit cooler than than Monterey, Mexico, the trees looks a bit unsightly in the winter, as they haphazardly color and shed leaves.
