Baltic Rush

Juncus balticus

CommonPlant
Illustration of Baltic Rush (Juncus balticus)

Baltic Rush is a rhizomatous native rush that spreads extensively by underground runners to form large, open colonies across a wide range of moist habitats from sea level to high mountain meadows. Its dark green, smooth, cylindrical stems grow 1–3 feet tall, and the flowers emerge in a loose cluster from the side of the stem. It is notably tolerant of alkaline, saline, and seasonally flooded soils, making it a key stabilizer of wetland edges, streambanks, and playas across the western United States. It is widely used in riparian restoration plantings.

Habitat
Wet meadows, stream banks, alkaline flats, coastal wetlands, and mountain meadows across western and northern North America.
Diet
Seeds eaten by ducks and marsh sparrows; rhizomatous colonies stabilize streambanks and provide cover for voles and other small mammals.
