DistributionMountains only. Known from just two sites in the Hot Springs area of Madison County. Specimens from Union County are misidentified and actually are C. lindheimerianus.

PA and WV to IA and NE, south to GA, northern FL, TX, AZ, and Mex. Many populations in Atlantic Coast states are adventive and not native, but the ones over limestone in Madison County are assumed to be native.
AbundanceVery rare. Of the two sites, at least one is still extant, with at least 30 plants counted in 2012. This is a State Endangered species.
HabitatDry soil, over limestone; requires high pH soil.
PhenologyFlowering and fruiting June-September.
IdentificationPrairie-tea Croton is a low (1-2 feet), spreading, many-branched semi-woody herb. Leaves are elliptical to rounded but less than 1 inch long, pale whitish green on the undersides, and densely hairy with stellate hairs. The numerous inflorescences are short (maximum of 1 cm) and congested racemes at leaf axils. This plant has a layered look, with horizontally spreading branches, often somewhat wider than tall (when often under 1 foot high).
Taxonomic CommentsNone

Other Common Name(s)One-seed Croton. Typically called just Prairie Tea, but this is a highly misleading common name; it is not a tea species, of course, and as other members of the genus Croton have the group name also of Croton, the best name is Prairie-tea Croton.
