Eryngium aquaticum

Phonetic Spelling
er-RIN-jee-um a-KWA-ti-kum
Description

Many of the common names for this plant are derived by its use by Native Americans as a treatment for snakebites.  

This native wildflower 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.  It can grow in loamy soil in garden areas where water is adequately applied. It prefers wet soil but will tolerate dry and once established is quite drought tolerant. It grows in full sun to part shade with the more sprawling habit in fertile soil or in too much shade. Taller plants may need support.  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 naturalizes easily through seed.

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

This plant does not tolerate root disturbance.
