A few sites that offer resources for gardeners in the Pacific NW and beyond:
Bellingham Food Bank’s Garden Project: Not only do they offer great volunteer opportunities for local gardeners who want to give back, they also have a really wonderful growing guide for local Whatcom County Growers
Great Plant Picks: A website dedicated to educating the public on plants that thrive in Pacific Northwest gardens, a fabulous resource for both beginning gardeners and old hands.
Elizabeth C. Miller Horticultural Library: Yes, Virginia there is a library just for gardeners. And it’s a great place to visit whenever you’re in Seattle. Even if you aren’t in the area, you can utilize their plant answer line and gardening answers knowledgebase for help with gardening questions.
Washington Native Plant Society : A 35 year-old institution that focuses on native plant conservation and advocacy. If you’re looking to I.D. some plants on your next hike, take a look at their native plant lists which cover hundreds of trails across the state. They also have suggestions for folks that want to grow natives in their backyard.
Territorial Seed Company : Founded by garden author and entrepreneur Steve Solomon, they were one of the first to offer seeds cultivated specifically for the rainy NW. Besides ordering seeds you might want to peruse their growing guides, or pick up one of their catalogs which also have a great deal of good advice.
Irish Eyes Garden Seeds: I’ve used their seed potatoes for several years now. I’m particularly fond of their Russian banana variety. Their site also gives you the lowdown on potato growing as well as other crops.
