Description: This creepy little riparian bog matt bears no resemblance to its eryngium brethren. Though home to hydric areas, it can surprisingly thrive in part shade in a fairly dry location. You'll fall on love with the tiny blue cone-shaped flowers. Natural habiatat includes swamps, bottomland forests, pond margins, streambanks, fens, swales and pastures.
