Juncus marginatus

Shore rush


This is a rush with leaf blades, so it looks quite different from the leafless stems of soft rush. It may be encountered along sandy, wet shores and ditches as single clumpy plants or as an abundant colony of plants. This Juncus is one of 21 occurring in Florida (Wunderlin, 2003). Shore rush is located throughout the northeast, the deep south, and extending into the southwest US; and in northeast Canada as well (Kartesz, 1999).


Shore rush is a true rush. Stems clump-forming, somewhat flattened, to 4 ft. tall; leaf blades flat, to 1/4 in. wide, pointed tips; inflorescences at stem tip, from very compact to much-branched and open, having several-200 clusters of flowers and fruits; flowers dark brown, stiff; seed capsules to 1/8 in. long, elliptic with rounded 3-lobed tops, reddish brown, shiny; seeds irregular, amber.
