Welcome to the 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 horticulture 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
• Classes & workshops
• Plant sales three times per year
• Bargains on hard-to-find seeds and gardening books
• 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. Volunteers are always welcome, so join a Border crew or pick a date from our Border Volunteer Schedule.

Timely Tips for Northwest Gardens

Do your fall bloomers flop? Do your Sedums sag? - Try cutting back plants such as Asters and tall Sedums (like 'Autumn Joy') by one-half now, before they set bloom buds. They will be shorter, bushier, and less likely to flop this fall.
