McCollum Park Demonstration Garden

600 128th St SE
Everett, WA 98208

McCollum Park was the first garden in the Snohomish County Park system. Volunteers created it in the 1960’s along with the Parks Department on what was once a landfill site. In 1984 WSU Snohomish County Extension moved into the administrative buildings and continue to occupy them to this day. Since then, WSU-Snohomish County Extension Master Gardeners have created a series of demonstration and teaching gardens surrounding the office buildings. These ever-changing gardens are funded by the Snohomish County Master Gardener Foundation and designed, planted and maintained by Snohomish County Master Gardeners. They demonstrate a variety of planting styles, themes, and techniques in the hope that visitors will learn something new, discover something wonderful, and most of all, truly enjoy their time visiting the McCollum Park Demonstration Garden.

  • Take I-5 to Exit #186 (128th St)
  • Go East on 128th St about ½ mile
  • Turn into McCollum Park located on right side of street
  • Proceed South in the park past the pool and ball fields.
