Balcony Garden

I've recently started a small balcony garden and am looking for plant suggestions. The balcony is recessed and gets about 1-2 hours of direct sun and is otherwise mostly shaded. I'm interested in plants that will survive wintering on the balcony (i.e. perennials). I'd also be interested in edible plants (herbs, vegitables) that can tolerate the low-ish light levels.

Also, if anybody knows about a good book or website on the subject suitable to the Vancouver climate I'd love to know about it.
