           2004 Professional Awards Jury Comments

The Trillium Projects began in 1994 with the idea of building a small native plant garden—only 500 square feet—on the grounds of a neglected WPA-style Parks and Recreation building. What was once a small, experimental garden is now the entrance to Seward Park, a 300-acre park with one of only three remaining old growth forests in Seattle. The efforts that began in Seward Park have continued with five additional projects now collectively referred to as the Trillium Projects, after the region’s native western trillium. The six sites form a network of landscapes, fine-tuned for environmental education that represent a succession of ecologies from the woods to the water's edge.
