The Urban Arboretum
The Urban Arboretum, maintained by Amazon Horticulture, provides Amazonians and community members a connection to nature in the center of Seattle's urban core. As you walk through Amazon's Puget Sound headquarters, we invite you to experience this urban botanical garden, which reflects the diverse plant palette represented within The Spheres.

The Frontier landscape was our final significant addition to Amazon’s Urban Arboretum. As its name suggests, the Frontier landscape embraces a West Coast Cascadia theme, inspired by the American Frontier and the Wild West.

In this landscape, you will find dwarf Oregon grape (Mahonia nervosa), evergreen huckleberry (Vaccinium ovatum), sword ferns (Polystichum munitum), meadow checkermallow (Sidalcea campestris), and white oaks (Quercus garryana), all species native to the Pacific Northwest. Native sedge meadow plantings around the building provide valuable urban habitat for native pollinators.
