J20150917-0018—Vitis californica—RPBG

Vitis californica—California wild grape. This is probably V. californica although their are no accession records at the garden for this particular specimen. It has been growing on a bridge across Wildcat Creek for many years. For doubters, the colors of the grapes are real. The grapes are going through what is called veraison (change of color of the grape berries.) See Wikipedia en.wikipedia.org/wiki/Veraison for more information. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.
