Comments

Baltic rush has been collected often all around the Watershed. It occupies mesic habitats from basin to subalpine: wet meadows, river and pond sides, ditches, etc. Juncus balticus tolerates alkaline soil, and is available from garden centers for ornamental use. The central USA range is all Western, upper Great Plains, Great Lakes, and northern New England states. The species runs throughout the Rio Grande drainage in New Mexico, with a few locations in far western Texas. Note that FNA still treats this taxon as a variety of Juncus arcticus, but POWO relegates Juncus arcticus var. balticus to Canada, Greenland, and the Eurasian arctic, and treats the mainland USA species as Juncus balticus.
