This year is really good for Oakland Mariposa Lily. I usually only see a handful, but this year when you see one you see dozens at a time. You can find them on Ring Mountain in Marin, and in Redwood Park on the south ridge, and in Tilden in Berkeley. The whole Calochortus family has beautiful flowers.
While looking for morels in the foothills, we found a 'snow plant,' a saprophytic plant like the sugar stick, but larger. Apparently when the snow plant is blooming, morels are around, so it is likely that we were a bit early for morels.
