Bellevue Demonstration Garden: 15500 SE 16th St., Bellevue

15500 SE 16th St

The King County Master Gardeners in cooperation with Bellevue Parks & Community Services manage the Lake Hills Greenbelt Urban Demonstration Garden also known as Bellevue Demonstration Garden. Established in 1984, this urban demonstration garden has grown from a single P-Patch surrounded by blackberries on a steep, rock-filled slope to the flourishing garden it is today.

The mission is to provide public education in gardening and home horticulture based on resources from Washington State University, and to create a solid learning experience for the volunteer. The goals are to demonstrate good gardening practices in a typical urban setting, involve Master Gardeners with the public at the garden using the garden setting and WSU resources and provide a practical hands-on educational resource for all Master Gardeners.

The garden includes a complete MG Diagnostic Plant Clinic, Master Compost Center, Greenhouse Operations, Children’s Garden, over 40 demonstration beds and gardens, Saturday Workshop Series for the general public from January through October and two major events (see details below); Spring Plant Sale in May and Harvest Festival/Plant Sale in September.


Open from dawn to dusk. Wheelchair accessible.
