NPA Border

The NPA Border at Bellevue Botanical Garden is a showcase for what grows best in our Northwest gardens. It is NPA's gift to the public, to share our passion for gardening and to inspire that passion in others.

The Botanical Garden is a top destination in the Seattle area, attracting hundreds of thousands of visitors each year, and there's no admission charge.     Learn More about BBG

The Border is a featured attraction at the garden, containing hundreds of varieties of perennials, bulbs, grasses, shrubs and trees. It is maintained entirely by NPA volunteers, a true labor of love and commitment to our community.

Visit often as the border changes through each season, offering year-round inspiration!     See Location Map

The NPA Border has been a featured attraction at the Bellevue Botanical Garden since the garden opened in 1992. Charles Price, Glenn Withey, Bob Lilly and Carrie Becker designed the original border. In 2008 a large project to incorporate stairs and paths through the Border was accomplished through a successful partnership between NPA and the Bellevue Botanical Garden, the City of Bellevue Parks Planning and Resource Management divisions, and the Bellevue Botanical Garden Society with Price and Withey doing the Border re-design. Today the Border continues to evolve as an example of a distinctly American-style mixed border, showcasing a diverse collection of perennials, bulbs, grasses, trees, and shrubs. The NPA Border is one of the largest public mixed borders in the country maintained by volunteers.
