Discussion | Alopecurus carolinianus is native to the central plains, Mississippi valley, and southeastern United States, where it is common in wet meadows, ditches, wetland edges, and other moist, open habitats; it is occasionally a weed of rice fields. At the northern limit of its range it is clearly adventive, growing in gardens and nurseries. It also occurs in arid areas of the prairies and southwest, growing sporadically along sloughs and in ditches and vernal pools. Whether such populations are native or naturalized is not clear.

Alopecurus creticus is native to marshes and wet places in the southern part of the Balkan Peninsula. It was discovered on ballast dumps in Philadelphia, Pennsylvania in the nineteenth century; it has not persisted in the Flora region.
