Bitter Snakeroot Eryngium aquaticum

Marsh eryngo is an herbaceous perennial wildflower that grows naturally in bogs, marshes, ditches, swamps and wet areas, especially where limestone can be found near the surface. It can be found growing in coastal locations from New Jersey, south to Florida and west to Mississippi. The species epethet is Latin for aquatic and refers to the plant’s preferred habitat. 

Marsh eryngo can grow in loamy soil in garden areas where water is adequately applied. It prefers wet soil but will tolerate drier soils and, once established, is quite drought tolerant. It grows in full sun to part shade with a more sprawling habit in fertile soil or in too much shade. Taller plants may need support. It naturalizes easily through seed. This plant does not tolerate root disturbance.  

The interesting foliage and flowers are great in cut and dried arrangements and can make this a specimen plant in your garden. Or plant in groups in low spots, near water gardens, rain gardens, ponds, or in borders. It is an excellent choice for pollinator and native gardens.

Insects, Diseases, and Other Plant Problems:  No serious issues. Overly fertile soils can lead to taller plants that can sprawl.
