When Kay Bullitt died in August 2021, Seattle Parks and Recreation took possession of her property where we are building the Cass Garden. Kay had deeded the property to SPR to become a city park. SPR has hired a consultant, Karen Kiest Landscape Architects, to lead a planning and design process to determine what kind of the park the public wants on the site. While this process proceeds, SPR has limited PlantAmnesty's access to the property and the Cass Turnbull Garden. With explicit SPR permission we are allowed to hold periodic work parties to maintain the plantings that have already been installed in the garden but have been instructed not to do any new work on the garden and to cease offering tours. To keep abreast of developments with the Cass Garden, request quarterly updates from info@plantamnesty.org. To keep informed of SPR's planning process, visit their website.

The Cass Turnbull Garden: Building a Resource for the Community

  • Honoring Cass Turnbull, PlantAmnesty's late founder and horticultural leader in the community
  • Supports PlantAmnesty's Mission: Provide Education, Resources, and Advocacy to Prevent Mal-pruning and Preserve Urban Greenspace
  • Located at Kay Bullitt's residence on Harvard Avenue East on Capitol Hill
  • A future Seattle Parks and Recreation public garden
