Discussion | Eragrostis curvula is native to southern Africa. It is often used for reclamation because it provides good ground cover but, once introduced, it easily escapes. In the Flora region, it grows on rocky slopes, at the margins of woods, along roadsides, and in waste ground, at 20-2400 m, usually in pine-oak woodlands, and yellow pine and mixed hardwood forests.

Eragrostis echinochloidea is native to southern Africa. It is now established in Arizona, growing in gravel soils, often along roadsides and in sidewalks, from 700-1000 m. It has also been found in Prince George's County, Maryland. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
