E. intregrifolium is a perennial forb/herb of the Apiaceae family that is native to North America. It has a long-lived life cycle. Average maximum root depth was found to be approximately 9.5 cm, and average root porosity was found to be 42 percent.
E. intregrifolium is found throughout the southeastern United States, as far west as Texas.  Within this distribution, it is distributed from southeast Virginia in Greensville county and eastern North Carolina, south to northeast Florida and the pandhandle, west to Texas and Oklahoma, and inland in central Tennessee.
Generally, E. integrifolium can be found in pine flatwoods, savannas, seepages, and other moist and nutrient-poor areas. Common habitats that many specimens have been collected from include roadside ditches, marshes, savanna pineland, pine flatwoods, wet flatwoods, and boggy wet depressions. Soils include wet and drying sandy loam, sandy peat, and other sandy wet soils. It is also listed by the USDA Natural Resources Conservation Service as a facultative wetland species, where it most often occurs in wetland habitats, but can also occasionally be found in non-wetland habitats. In Florida, it is also considered an indicator species of the panhandle seepage savannas.
Associated species include Juncus trigonocarpus, Sarracenia leucophylla, Aristida palustris, Sphagnum sp., Lobelia georgiana, Oxypolus sp., Coreopsis sp., Buchnera floridana, Hypericum opacum, Xyris elliottii, Habenaria integra, Polygala ramosa, Polygala lutea, Ctenium aromaticum, Hibiscus aculeatus, Macranthera flammea, and Arnoglossum sulcatum.
Eryngium intergrifolium is an indicator species for the Panhandle Seepage Savannas community type as described in Carr et al. (2010).
It has been observed to occur in habitats that are commonly burned.
This species is considered to be of special value to native bees since it attracts large numbers of native bees to pollinate.
Conservation, cultivation, and restoration
This species is listed as endangered by the Kentucky State Nature Preserves Commission. It is also considered critically imperiled in the states of Virginia, Kentucky, Tennessee, and Oklahoma, and is considered imperiled in Arkansas.
