Taxonomic notes

Synonyms: none.[1]

Varieties: none.[1]


E. aromaticum is a low growing, perennial herb that can be found as a basal rosette of slightly spiny, deeply dissected leaves through out most of the year. It has a carrot like taproot.[2] Leaves are simple and alternate.[3]

According to Diaz-Torbio and Putz (2021), Eryngium aromaticum has taproots with a below-ground to above-ground biomass ratio of 1.6 and nonstructural carbohydrate concentration of 86.3 mg g-1.[4]


It is found throughout the peninsula and panhandle of Florida, along with parts of eastern Georgia and southern Alabama.[2]



E. aromaticum has been found in loamy sand and peaty sand type habitats such as scrub, sand ridges, sandhills, flatwoods, open pinewoods, pine-oak woodland, and slash pine savannah. It is also found in disturbed areas including powerline corridors, disturbed slash pine forests, roadsides, and clear cut flatwood forests.[5]

E. aromaticum was found to increase in frequency in response to soil disturbance by clearcutting and chopping in north Florida flatwoods. It has shown regrowth in reestablished native flatwood habitat that was disturbed by these practices.[6] Associated species: Agalinis plukenetii, Liatris provincialis, Chrysopsis gossypina, C. linearifolia, Polygonella gracile, P. polygoma, P. fimbriata, Aristida stricta, Pinus clausa, Pinus palustris, Quercus virginiana, Quercus laevis, and Serenoa repens.[5]


It produces thistle-shaped flowers arranged in umbels and achene fruit[3]. It has been observed flowering and fruiting from June through December. [5]


Eryngium aromaticum is visited by sweat bees from the Halictidae family (Lasioglossum placidensis), thread-waisted wasps from the Sphecidae family (Tachysphex similis), and wasps from the Vespidae family (Stenodynerus fundatiformis).[7]

Herbivory and toxicology

Additionally, E. aromaticum is used as larval food by the Eastern black swallowtail butterfly[2].
