I sell wild foods for a living. The best guide out there for the Pacific NW is Discovering Wild plants by Janice Schofield. Hands down.
Just skimmed through that with what Amazon has to offer for previews, and that actually looks like one of the best ones Ive came across, Thanks for the referral.
It has pictures AND drawings, with detailed descriptions and where to finds...

Think this will be the winner.
Appreciate it Pianaoman..
