Welcome to NPA

The Northwest Perennial Alliance (NPA) is one of the largest nonprofit gardening organizations in Washington. Our mission is to help gardeners learn more about perennials and hardy plants that will thrive in the Pacific Northwest. We offer a wide range of activities, all run by volunteers:

• Free garden tours from April-October
• Free lectures by world class speakers
• Free newsletter, The Perennial Post
• Plant sales three times per year
• Bargains on hard-to-find seeds
• Neighborhood groups, a network of NPA garden clubs in Seattle, Bellevue, Redmond, Everett, Tacoma, Olympia, Gig Harbor, Whidbey Island and many other areas.
• Nursery discounts at select nurseries with your membership card.
  

We also maintain one of the premier perennial gardens in the U.S., the NPA Border at the Bellevue Botanical Garden. In 2008, we began a major, two-year renovation of the Border. If you’d like to help, please join a Border crew or make a donation.
