Incredible Edibles

Las Pilitas is not responsible for indigestion or death due to eating plant parts!

This list represents historical data, Eat at your own risk! Don't crawl out of the hospital and yell at us, we're just listing information.

Many of these plants cause severe allergic reactions, convulsions and death. Two books are a must if you wish to include some of these plants in classes South Fuller, Thomas C., and Elizabeth McClintock, 1986. Poisonous Plants of California. California Natural History Guides 53. University of California Press, South Los Angeles AND Wild Edible Plants, Kirk, 1975, Nature graph(there is a newer version out).
I've sampled many, if not most of these, most just taste bad.
