Diagnostic Characteristics:
Species in the genus Eryngium have flowers in dense capitate heads with white to blue petals. This species is distinguished by the blue colored heads and their size (less than 1 cm long and smaller than E. yuccifolium). Plants are erect and flower heads are at the end of the stems. Leaves are variable in shape from lanceolate - elliptic or ovate and but generally to 10 cm long and have variable and wavy margins that are sometimes spinose.

Changes in moisture/hydrologic conditions of the habitat for this species would likely be detrimental. Changes could result from overstory removal, stream/wetland alteration or impacts due to erosion or soil deposition. Exotic pest plants are a threat to this species.
