The Northwest Perennial Alliance is a nonprofit volunteer organization for everyone who is passionate about gardening in the Pacific Northwest.
We are devoted to teaching, inspiring, and sharing the joy of gardening.
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.
Join NPA to tour our member's fantastic Open Gardens, where you'll find many wonderful ideas for your own garden! Most are private gardens not usually open to the public, located throughout the Puget Sound region of Washington.
