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.

Doppler Stairway

Doppler staircase

Right now, you should be standing at the base of the Amazon Doppler stairway along 7th Avenue. Completed in 2015, while The Spheres was in the early stages of design, Doppler was the first landscape to be installed in what would eventually become Amazon's Urban Arboretum.

The fern-filled woodland landscape of the mid-block corridor hosts a variety of seasonal surprises, from the iridescent blue berries of the evergreen hydrangea (Dichroa febrifuga) to the bold foliage, mysterious flowers, and radiant fruit of the Himalaya cobra lily (Arisaema consanguineum). The lush planting beds are complemented by the sculpture Petros by Julie Spiedel that towers above you.
