Quercus cerris | Central Valley

For a special project, cuttings were taken from the tree shown on the previous page. 15 years of observation suggest that, of the two trees, the one on left in the Grove picture produces very few, or no, acorns each year. The tree on the right produces viable acorns regularly. Seedlings were grown from the productive tree, then, using a special technique, scion from the non-productive and beautifully-shaped tree were grafted to the seedling rootstocks. These grafted oaks have grown for 5 years with minimal losses. But at least one of the grafted trees is showing some variegated foliage. Upon investigation, such variegated foliage was also found on the Shields mother Turkey Oak.
