DistributionThroughout the state; quite possibly in every county.

According to FNA, native of North and South America, but the original extent of the range is unclear. Currently in N.A found from Que. to Ont. south to FL and TX; scattered westward. Believed to not be native in most of the U.S.
AbundanceFrequent to common throughout the Coastal Plain, Sandhills, and Piedmont; uncommon to fairly common in the Mountains.
HabitatRoadsides, railroad margins, fields, cropfields, waste ground, vacant lots, barnyards.
PhenologyFlowering and fruiting June-October.
IdentificationMexican-tea is closely similar to American Wormseed (D. anthelmintica), but that plant has tiny and poorly developed leafy bracts (vs. well-developed in Mexican-tea). This distinction should be obvious in the field -- as Mexican-tea has distinct "leaves" embedded within the inflorescence and American Wormseed is "leafless" amid the flower clusters.
Taxonomic CommentsLong known as Chenopodium ambrosioides.
