About the NPA Border

NPA's amazing perennial border at Bellevue Botanical Garden (BBG) is a showcase for what works best in Northwest gardens. Come revel in thousands of perennials, shrubs, bulbs, evergreens and trees that provide color and beauty year round. Stroll the paths, relax on the benches and enjoy one of the largest public perennial gardens in the country maintained entirely by volunteers. The Border has been a featured attraction at BBG since the park opened in 1992. It is a source of education and hands-on learning opportunities for NPA members, horticulture students and gardeners throughout the Puget Sound area. BBG is free and open to the public daily, dawn to dusk. Driving directions.

Volunteers make the difference

NPA depends on volunteers to keep the Border beautiful. Volunteering a few hours is the ideal way to expand your knowledge about gardening while giving back to the community. You'lll usually find our volunteer crews in the Border at 10 a.m. on Thursdays. We welcome all NPA members, garden enthusiasts, students and community service groups. Please join us!
