Shields Grove Davis
The University of Utah isn’t the only place with Cottam hybrids. This tag shows a Cottam hybrid in the Shields Oak Grove at the Univ. of California in Davis. Dr. Cottam worked closely with the excellent horticulturists at Davis, and together they created the largest collection of oaks west of the Mississippi in the United States. Many Cottam oaks are present in the Shields Grove, and have attained much greater size than their siblings at the Univ. of Utah, owing to the vastly deeper soils in Davis.
