Left to right, Landscape Architecture Professor Daniel Winterbottom and students David Knight, Michael Dalquist and George Wittren put the finishing touches on the UW’s prize-winning exhibit at the Northwest Flower & Garden show. The UW project, titled “Throwaway Spaces: Building Community Through Urban Gardens,” took the huge show’s highest honors: the Founder’s Cup and Sunset Western Living Award. The student-designed display imagines the results of immigrants bringing different cultural backgrounds to revitalize derelict urban spaces, using found objects and recyclable materials. It features a bamboo-lined waterfall, Mexican style plaza and Ukokkei hens (traditionally believed to have curative properties). The annual show — one of the nation’s largest — occupies 8 acres of the Washington State Convention Center in downtown Seattle through Sunday.
