| Distribution | Collected 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. | |
| Abundance | Rare. 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. | |
| Habitat | Cropfields, primarily corn; weed in garden. | |
| Phenology | Flowering and fruiting July-September. | |
| Identification | Asiatic 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. | |
