Additional Information about Andropogon virginicus

Native to Ontario 

Warm Season Grasses: These grasses are much slower starting in the spring. They do not push new growth until temperatures warm in early to midsummer. They flower later in the summer or fall with most blooms remaining into the winter. Most warm season grasses tolerate heat, humidity and drought; some even thrive in these conditions.

This aggressive species thrives in poor soils, tolerates a range of habitats, is less palatable to grazing animals than other pasture plants, and competes by one method of allelopathy; it releases herbicidal chemicals from its dying tissues.
