I live on the peninsula, bay area, northern california, san mateo county. I would like to identify these plants, to see if there are uses for them.

The second one, IMG_0242.JPG, is wild geranium.  I eat it raw (small amounts) and cooked and am making a tincture out of the roots; see http://www.eattheweeds.com/www.EatTheWeeds.Com/EatTheWeeds.com/Entries/1937/7/24_Stork’s_Bill,_Cranesbill.html. ;

If no one responds on the fourth pic, I'll look it up in my notes (not currently handy).  If it's the one I have in my yard, leaves when young are edible.  The first pic almost looks like my sorrels but it's hard to tell from that single pic and angle.  I don't recall ever seeing the third one, sorry.

Thank you very much. The fisrt pic, the leaves are quite long when full grown, approx. 12-20 inches long. I will take some better pictures and post them later.

This is the same plant as pic #1

The first one is yellow dock (rumex crispus), the third one I can't tell without a closer look at the flowers, and the last one looks to be cat's ear, but I'm no 100% sure, how long are the leaves? (it is most definitely in the aster family)

Mingo: I double checked the info you gave me. It looks to be correct from the descriptions I read. The cats ear one the leaves are about 6-8 inches long. I'll try to take a picture of the flowers of the 3rd one.
Thanks

Rehashing an old thread, but at the very bottom center of the first photograph there's a little raspberry plant.  I don't know what the others are, but that's definitely raspberry.
