Description:
Gattinger prairie clover is a sprawling perennial herb with numerous branches up to 20 inches in length. The species has pinnately compound leaves with 5 to 7 leaflets, but may have 9. From July to September, rose-purple flowers develop on long cylindrical heads (spikes). The flower spikes are mostly more than 2.5 cm in length and may grow up to 7.5 cm, loosening post-anthesis and losing most of the interfloral bracts. The calyx is pubescent antrorse. Peduncles are less than 3 cm in length (Carman 2001 and Allison and Stevens 2003).
Habitat:
Gattinger prairie clover is a narrow endemic to dry calcareous, rocky, limestone glades and barrens that occur mainly in two areas: northwestern Alabama and north central Tennessee (NatureServe 2003 and Carman 2001). An outlying population occurs in northeast Alabama and it is also rare in Georgia, Arkansas and Missouri (NatureServe 2003). The plants pictured on this page were photographed in Walker County, Georgia.
Range:
Gattinger prairie clover is found in northwestern Alabama, north-central Tennessee, northwestern Georgia, Arkansas, and Missouri.
