Your selection of shade loving plants for this area is huge. Any of the better shade gardening books will be a source of inspiration - "The Complete Shade Gardner" by George Shenck or "The Natural Shade Garden" by Ken Druse are two of my favorites. The Sunset publication "Gardening in the Pacific Northwest" is also a good choice but is not dedicated to shade gardening. Also, most of the better area nurseries will have a great selection of shade plants for this area in stock with the largest selelction in about April. Emery's Garden in Lynnwood is also offering a shade gardening weekend this spring with seminars and sales on shade plants. Not sure of the date but if you give them a call they will let you know when it is scheduled.

"Made in the Shade" is available for a song on eBay, and it is the best - terrific organization, great plants recommendations, and even a chapter on deer. As long as it's winter and we're reading instead of gardening, check out Ken Druse's newest (I think) "Passion for Plants".
