Bidwell's Bar is an example of the type of oranges that were most commonly grown in California before the Washington navel orange arrived on the scene.  The original Bidwell’s Bar tree was planted in 1856 in Butte County, California and is often called the “Mother Orange Tree.”  It is still alive and is believed to be the oldest living orange tree in California.
