Jennings Park Demonstration GardenAred and orange rose in full bloom, from the Jennings Park MG Demonstration Garden.

Described by Horticulture Expert Ed Hume as one of the finest Master Gardener Demonstration Gardens that he had ever visited, the Jennings Park Demonstration Garden is easily accessible all year around to the public just a mile from Interstate 5 in Marysville.

The half-acre garden consists of an integrated mix of perennial, annual, and edible beds featuring a variety of gardening practices and ideas, most of which can easily be incorporated into your own landscaping. Or the garden can simply be enjoyed within the tranquility of the park.

Visit the English, Rose and Cutting Gardens; come see what’s new in the Vegetable Gardens; let the little ones play Hopscotch in the Walkable Garden; explore the vertical garden area; and look at all the beds with Dwarf Conifers, Heucheras, Hostas, Grasses, and much more,


While the garden itself is open year-round, volunteers are available to answer questions, explain techniques, and help solve home garden problems every week May through September on Mondays and many Wednesdays 9 am to noon (excluding holidays). Call 425-357-6010 for an exact schedule.


Use the main entrance to Jennings Park at 6915 Armar Road in Marysville. The demonstration garden is southeast of the parking area just beyond the Children’s play area.


Take exit 199 from I-5; drive east 3/4 of a mile on 4th Street; turn left on 47th. Continue 1/2 mile, bearing right at the Y; look for the park entrance on the right.

Evergreen Arboretum Demonstration Garden BorderA raised garden bed with a cement retaining wall borders a cement path with purple,red, green, yellow and orange plants.

Originally designed and built by Master Gardeners in 1992, this demonstration garden border was part of the north Everett arsenic mitigation project, which removed the contaminated topsoil and all plants in the Evergreen Arboretum at Legion Memorial Park. Once the project was complete in the fall of 2016 and new irrigation installed, the 200-foot border was redesigned and planted by Master Gardeners and is in the process of returning to its original splendor. It is known as one of the jewels of the Evergreen Arboretum and well known around Puget Sound for both its educational value to the residential gardener and its beauty as a display garden. The project is a collaboration between the Washington State University – Snohomish County Master Gardener Program, the Evergreen Arboretum & Gardens Foundation, and the Everett Parks and Recreation Department. For more information and a photo tour, please visit the Arboretum website.
