AuthorMueller of Aargau
DistributionWidespread from the coast through the Piedmont; scarce in the Mountains. Since the variety septentrionalis is native exclusively to the US and northeastern Mexico, it could be argued that NC plants could be treated as natives. However, the pre-Columbian range is unclear, and Weakley (2018) considers it as not native in the Southeastern states.

The species in general is native of the New World; this variety is perhaps native from NJ to MN and NE, south to FL, TX, and northeastern Mex.
AbundanceGenerally common, escept rare in the Mountains.
HabitatDry sandy soil of roadsides, cropfields, old fields, pastures, waste places, weedy lots, clearings, scrapes, etc.
PhenologyFlowering and fruiting May-November.
IdentificationTooth-leaved Croton usually grows 1-2 feet tall (maximum of 3 feet), moderately branched. The leaves are narrowly elliptical to oblong, 2-7 cm long, the margins crenate-serrate, both surfaces moderately stellate-hairy. The toothed leaf margins separate it from our other species of Croton.
