Join the NPA

The NPA is a group of gardeners with a passion for herbaceous plants.  Members represent a wide range of gardeners, professional and amateur, who all share the aim of furthering perennial gardening in the Northwest. Members enjoy free garden tours of more than 80 private gardens not open to the public, lectures by well-known gardeners from around the world, classes, and an opportunity to join a neighborhood garden group.  Meetings are held on the third Sunday in September, November, and January.  A membership covers both you and a spouse or significant other living at the same address and runs from Jaunuary - December. If you own a garden related business and would like that name included with your membership, please contact our office administrator.
