DistributionCollected from 5 adjacent counties in the southern Coastal Plain. Mapped by BONAP in Pender County. Also reported from Duplin, Harnett, Hoke, Pender, Richmond, and Sampson counties in a journal note in Rhodora 60:290.

Native of the Old World; in N.A. only in NC and SC.
AbundanceRare. This is a target of an eradication program by the USDA owing to being a parasite on some grain species -- such as corn, rice, sugar cane, sorghum, and others -- and affecting the yield of them.
HabitatCropfields, primarily corn; weed in garden.
PhenologyFlowering and fruiting July-September.
IdentificationAsiatic Witchweed is a slender plant up to 15 inches tall, with slender opposite leaves, and it may also have strongly ascending branches. The flowers are bright red, 9-11 mm long, tubular and with 5 flaring lobes; perhaps only Cardinal-flower (Lobelia cardinalis) can match its flower color in NC.
