Swamp lantern (also unflatteringly called skunk cabbage) lines the path. Although its scent is considered quite unpleasant by some, its beautiful yellow color in spring will light the way. If you really don't like the smell, feel free to substitute. False lily of the valley can spread aggressively but will not out compete the larger shrubs nearby. Cascara and vine maple will do well in the drier areas of the wet zone. Most of these trees and shrubs cannot survive year-round standing water.
