| Family | Scientific Name | Common Name | Habitat | Distribution | Image |
|---|---|---|---|---|---|
| Asteraceae | Echinacea angustifolia var. angustifolia | Narrow-leaved Purple Coneflower | Dry prairies, barrens, glades. | MB and SK couth to w. LA, c. TX, c. NM, and ne. AZ. | |
| Asteraceae | Echinacea angustifolia var. strigosa | Prairies. | S. KS south through OK to nc. TX, largely east of the distribution of Echinacea angustifolia var. angustifolia. | ||
| Asteraceae | Echinacea atrorubens | Topeka Purple Coneflower | Tallgrass and blackland prairies, limestone and sandstone glades and woodlands. | E. KS south through OK to se. TX. | |
| Asteraceae | Echinacea laevigata | Smooth Purple Coneflower | Open woodlands and glades over mafic or calcareous rocks, such as diabase, limestone, and dolostone, rarely in oak-pine savannas of the upper Coastal Plain over circumneutral clay sediments. | c. and w. VA south through c. NC to c. and w. SC and ne. GA; disjunct in Piedmont of PA (where extirpated). |  |
| Asteraceae | Echinacea pallida | Pale Purple Coneflower | Dry prairies, open dry woodlands, roadsides (introduced eastwards in our area). | ON west to MI, WI, and ne. NE, south to IN, LA, and TX; disjunct eastward in TN, AL, GA, SC, NC, and VA (where probably but uncertainly native). |  |
| Asteraceae | Echinacea paradoxa var. neglecta | Arbuckle Purple Coneflower, Bush's Purple Coneflower, Neglected Coneflower, Wallflower Coneflower | Rocky prairies and woodlands. | Endemic to the Arbuckle Mountains, OK; reported for se. TX (Kartesz 2015, 2021); reported for TX from an 1843 Lindheimer specimen without locality. | |
| Asteraceae | Echinacea paradoxa var. paradoxa | Yellow Coneflower | Limestone and dolomite glades, prairies, and savannas. | Ozarks of MO, n. AR, and ne. OK. |  |
| Asteraceae | Echinacea purpurea | Eastern Purple Coneflower | Open woodlands, roadsides, some of the occurrences persistent or spread from cultivation. | OH, WI, and IA south to Panhandle FL and TX; introduced more broadly as in ne. United States and ON, the exact limits of the native distribution unclear. |  |
| Asteraceae | Echinacea sanguinea | Sanguine Purple Coneflower, Happy Coneflower | Sandy prairies and longleaf and shortleaf pinelands. | Sw. AR and se. OK south to s. LA and e. TX. |  |
| Asteraceae | Echinacea simulata | Prairie Purple Coneflower, Glade Coneflower | Prairies, dry open woodlands, roadsides. | IN, IL, and MO south to KY, TN, and n. AR; some of the more eastern disjunct populations previously considered to be E. pallida are actually E. simulata; additional work is needed to disentangle the relative distributions of these two species in our area. GA native populations (Floyd Co.) are E. simulata. |  |
| Asteraceae | Echinacea tennesseensis | Tennessee Purple Coneflower | Calcareous glades. | Endemic to the Nashville Basin of c. TN (Davidson, Rutherford, & Wilson counties) (Chester, Wofford, & Kral 1997). |  |
