Coast man-root / Wild cucumber
(Marah oreganus)
Manroot is found wherever there is alder, red elderberry, salmonberry or thimbleberry to climb. In summer, man-root vines twine quickly onto shrubs, tree trunks and lower branches, clothing them in lush green. By winter, they die back to a large tuber just below the soil.
