Poison Oak
Toxicodendron diversilobum / Cashew Family
Saratoga, CA
July 7, 2008

This is another plant that everyone who lives or travels in the western states needs to learn to recognize and avoid. It is related to Poison Ivy and Poison Sumac and causes the same miserable rash in many people. It can grow like a large shrub or a vine. In the fall (or when stressed during a drought) the leaves turn a brilliant red and burgundy.


formerly known as Rhus diversiloba
