DistributionStatewide, though lacking collections from several contiguous counties in the southern Coastal Plain, where it is less numerous.

This is a widespread and numerous species in the East, from eastern Canada south to northern FL and eastern TX.
AbundanceCommon statewide, except uncommon (apparently) in the far southern Coastal Plain.
HabitatAs with most other members of the genus, it is found in disturbed ground in sunny places, despite it being a native species. It grows in lawns, on roadsides, in waste lots, and in other weedy places.
PhenologyBlooms and fruits from June to frost.
IdentificationThis is the familiar broad-leaved member of the genus, as the several basal leaves ascend or spread from the plant base on petioles 1-2" long. The blade is widely elliptical, strongly parallel-veined, about 4" long and 2" wide. The several scapes grow to about 8" tall, with the spike of tiny flowers covering the upper 50-60% of the stalk. The bracts are short and thus the spike is quite narrow, usually less than 1/4" wide. No other native Plantago is similar, though the non-native P. major, infrequent in the state, is similar; that species has ovoid to globose capsules, about 2-4 mm long, whereas P. rugelii has capsules longer and ellipsoid in shape, about 3-6 mm long.
