You can eat these if you catch them before they flower. Actually, you can eat them after they flower, too, but they don't taste as good. They grow all along the trails and roadsides in La Honda. My kids used to gather them, and they make a lovely salad - sweet and fresh. During the gold rush the forty-niners appreciated them. Fresh food was always the real California gold.
