Tough to grow any edibles under those restricted light conditions. May be better to focus on ornamentals here and try edibles in containers that can be moved into a sunnier aspect.

My sister lives in similar conditions and gardens under similar circumstances (Dana Point). Plants that thrive for her are azaleas, hydrangeas, hosta, ferns, liriope potted bamboo and camellias. In the sunniest locations she has gardenias and geraniums in containers.

This book helped me out a lot when I wanted to expand our shade gardens. Year round interest is possible and foliage can be beautiful especially in your zone!

In another garden we have everbearing strawberries that are partly shaded by fruit trees in summer, but produce a good 1st crop. If you have a sunnier location you can get ideas on the square foot gardening forum for edible plants.
