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.

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
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.
