Native California Edibles?

As much as I admire people who keep gardens full of California natives, I know I will always have at least 50% exotics in my garden because I love fruit. I was talking with a non-gardener and he asked me what there was in the way of native California edibles that are tasty at all and I had precious few answers.

native CA blackberry, thimbleberry, beach strawberry, hazelnuts

I don't think I'd find acorns tasty but I know it was a staple of native Californians. What else is there?

Here's a list from Las Pilitas of historical edible/medicinal uses of natives, not too much on here that I personally would want to eat, but you may find a few at least to add to your list.

Wild dandelion greens.
Wild mustard greens.

Our landscape is primarily CA natives, but I put food plants in a different category - we have to be practical! :-)
I have two guava trees in pots I bought specially for our parrots - and they don't eat the fruit - stinkers. Next year we will have apples. I also have my exotics, but I try not to plant things that will impact the natives and most of them stay in pots or near the house.

California wild rose hips are good when they are very ripe. They taste like what a rose smells like, if you can picture that.

There is some kind of gooseberry that I found one time that tasted like an apricot.

Miner's lettuce tastes like snow peas.

I like to chew on a leaf of yerba santa. (DH thinks it's awful.)

I think that Mexican elderberries are pretty good and they make good pie. It is reported that eating the berries raw will give you loose bowels, but I've never had a problem.

The seeds of the bush sages are edible.

Acorns (valley oak) taste something like chestnuts but without the sweetness of a chestnut.

The western walnut is small but tastes like a walnut.

Yep, I'll try just about anything.
