Quercus mexicana | Central Valley

Here we see Quercus mexicana, Tezahuatl Live Oak, growing in a Central Valley nursery. There are several examples of this species growing in the Shields Grove, and they have grown well in that location, despite drought and a lack of supplemental irrigation, but with the advantage of the deep soils for what Davis is known. The trees have proven to be truly semi-evergreen in the California climate, losing most of their leaves by mid-winter, and remaining largely bare until the spring burst of new growth. The leaves present as almost black green in color. Young trees bear a striking structural similarity to Japanese maple, giving a rare "layered" effect.
