The Master Gardeners of King County maintain ten demonstration gardens, three youth gardens and one outreach garden. In each of these gardens, the community can see firsthand the types of plants that grow well in our area and learn recommended planting practices and overall garden care. Visitors can also enjoy each garden’s unique beauty and large variety of plants. Old favorites grow alongside new experimental varieties. Find the locations of all the gardens on the page King County Master Gardeners map.

In addition to MGFKC demonstration gardens, we have included a list of the public gardens in King County and the surrounding area that we encourage you to visit to inspire, inform, and excite you about the beauty of plants for your gardens and their many medicinal, cultural and edible characteristics.


Animal Acres Demonstration Garden

Animal Acres Demonstration Garden

Located in the Pfingst Animal Acres Park, at NE 178th St and Brookside Boulevard, south of the intersection.

Small garden located within a city park, it showcases how to integrate organically-grown food crops, ornamentals and natives in a small space. A drip irrigation system shows how to better use and conserve water. Master Gardeners also promote environmental stewardship by maintaining pollinator-friendly areas, mixing native species and other perennials.
Produce (vegetables, fruits and herbs) is donated to local Northshore programs aimed at increasing food security.


Bellevue Demonstration Garden

Basil and other herbs at the Bellevue Demo Garden

Located on SE 16th Street between 148th Avenue SE and 156th Avenue SE, just west of 156th.

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 hands-on garden is an effective way for Master Gardeners to demonstrate gardening techniques to the community. The garden includes ornamental theme beds, a Northwest cactus garden, a children’s garden, vegetable gardens and more.

Carkeek Park Demonstration Gardens

Carkeek Park Demonstration Garden

Location: 950 NW Carkeek Park Rd, Seattle, WA 98177

Directions: From the main entrance, turn right immediately into the parking area.

The Carkeek Park Demonstration Gardens were designed first in 1996 to surround the Visitors Center. In 2015, it became the largest Master Gardener Demonstration Garden in King County maintained by volunteer all-season gardeners. Now an acre of themed beds joined together by gravel paths, they border a meadow, coastal forest, and the Park’s six-mile trail system.

A one-of-a-kind Seattle park feature, the Gardens’ mission is to help home gardeners envision a backyard wildlife habitat by using natives and adapted non-natives in an informal landscape style. Our plant diversity helps support migratory bird populations and pollinators by providing food, shelter, and nesting materials. As a teaching garden, Master Gardeners and horticulture students can attend gardening sessions and workshops. From the Shady Woodland Garden to the Ethnobotany Garden, visitors can see a wide variety of plants that thrive without fertilizers, pesticides, or herbicides—protecting the Piper’s Creek Watershed and salmon habitat.

Many of the gravel paths are wheelchair accessible with the exception of the gardens that surround the Environmental Learning Center, some of which can be viewed from the paved driveway. There are two picnic tables on the north side of the Visitors Center.

Thyme Patch Park is a display garden on a city lot neighborhood park located in Ballard. Part of the Seattle Park System, the Park features 14 P-Patch plots on the south half and a landscaped display garden maintained by Master Gardeners on the north half. After two years of planning, in January 2003 Master Gardeners began building the planting design for their landscaped portion of the Park.

Vashon Community Food Bank Garden

Located at Sunrise Ridge, 10030 SW 210th Street, Vashon Island.

This garden was designated as a Master Gardener demonstration garden in 2017 and now has 17 beds for planting plus a hoop house. The gardeners work in concert with the food bank volunteer coordinator to schedule work parties to clear and weed the gardens, install the drip irrigation systems, plant the vegetable seeds and starts from local organic gardeners and care for and harvest the food. Please note: The garden is open to the public during the daylight times and can be accessed through a latched gate. If you visit, please make sure the gate is closed and latched due to the problem of deer.

Ronald McDonald House Outreach Garden

Located at 5130 40th Avenue NE, Seattle.

Master Gardeners began this outreach garden project in the fall of 2005. There are two locations, a block apart, each with gardens. The older house had overgrown landscaping originally planted in 1983. The gardens at the newer houses were established in 2003. Master Gardeners have renewed and renovated established areas and created a number of individual focus gardens including two vegetable gardens, a giant pumpkin patch, a shade garden, a drought tolerant garden, a sun loving garden to provide brilliant colors and attract pollinators, and a patio garden. We have placed signage in individual gardens to invite people to pause to enjoy the plants and ask us questions.

Magnuson Children’s Garden

Magnuson Children’s Garden

Located behind the Magnuson Park Brig building, at 6344 NE 74th St, Seattle.

This garden has been created with ideas from the hearts and minds of local children and their parents, beginning in 2001.  Those ideas were put together in a design for a 1/4-acre site by the Children’s Garden Committee, a volunteer team of MGs and other horticultural experts.  The committee manages the garden, guides community volunteers and organizations in stewardship events and major projects and hosts free family programs from spring to fall.  Over the past 18 years, the garden has grown into a local treasure, filled with delightful features such as a life-size Grey Whale Garden, spiral paths that lead up to a Lookout and a Rolling Hill, a Starfish Garden, Willow House, Salmon Survival Path, Pollinator Garden, and much more.
