Acorn Festival - November 20

Sunday, November 20, 11 a.m.-3 p.m.

Fall is a time of harvest and festivities for the people of Southern California, as acorns from the live oak (Quercus agrifolia) were traditionally an important major food source. In honor of this, Native American dancers and tribal leaders join us to celebrate our connections with California native plants. (Dancers will demonstrate various dances intermittently throughout the day.) There will also be an artisans' marketplace. 

The Acorn Festival takes place rain or shine!

This event is free with Garden admission. Some activities require a small materials fee.
