More plants to add:
Pink Wood Sorrel (Oxalis Articulata) is an herbaceous perennial with clover like leaves. The whole plant is edible: leaves used raw in salads or cooked, flowers are sweet and can be eaten raw or added to tea. *Note: contains oxalic acid (like spinach and broccoli) which blocks absorption of calcium.
Buckbrush (Ceanothus Cuneatus) is a medium sized shrub with snowball type flower clusters. Leaves and flowers make an excellent tea.
*Edit* Adding Snowbrush Ceanothus (Ceanothus Velutinus). For edible uses, a superior Ceanothus with potently sweet fragrant leaves. Otherwise the same as Buckbrush.
English/Cherry Laurel (Prunus laurocerasus) grows as a large shrub though some cultivars are quite small. Fruit is edible when completely ripe and tastes similar to cherries. *Note: if you look for information on the edibility of Cherry Laurel, you'll certainly find warnings of its toxicity. Its leaves, seeds, and unripe fruit contain cyanogenic glycosides which can cause cyanide poisoning. Now, that sounds scary... but it's really not. Cherry Laurel actually has low levels of cyanogenic glycosides compared to other species in the genus, Prunus: Apricots, Peaches, Nectarines, Plums, Cherries, and Almonds. As we know, these are most certainly edible, but don't eat the leaves, seeds, or unripe fruit.
Course we'll know better which I have when the dang thing blooms next year. 
It was given the name 'yew' as a reference to the similar leaves and bark.
