Varieties: none.[1]
Description
L. virginica is a perennial graminoid of the Poaceae family native to North America.[2]
Distribution
L. virginica is found throughout the Eastern and Midwestern United States, Ontario, and Quebec.[2]
Ecology
Habitat
L. virginica can be found in floodplain forests, swamps, and streambanks.[3] Specimens have been collected in habitats such as shaded wet soils, drying sandy loam, shaded woods, mesic hardwood regions, floodplain bluffs, wet banks of rivers, and hammocks.[4] L. virginica is commonly found in an ideal habitat of partially shaded wet lowlands. It prefers moist soil with a high amount of organic matter that is commonly found along water bodies. It is not tolerant to droughts.[2]
Phenology
This species has been observed flowering July through October.[2][5]
Seed dispersal
This species is thought to be dispersed by gravity.[6] Seeds are typically dispersed in the summer through to the fall.[2]
Seed bank and germination
Seeds have bene classified as having medium vigor.[2]
Fire ecology
L. virginica is not fire resistant.[2]
Herbivory and toxicology
L. virginica can be used by grazing and browsing animals though it is not commonly found in the pasture areas that they inhabit. The Northern Pearly Eye butterfly caterpillar will feed on the foliage of the plant.[2]
