Discussion | Melica ciliata is grown as an ornamental in North America and is not known to have escaped. It is native to Europe, northern Africa, and southwestern Asia, where it grows on damp to somewhat dry soils. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Melica smithii grows in cool, moist woods from British Columbia and Alberta south to Oregon and Wyoming and, as a disjunct, from the Great Lakes region to western Quebec. It often forms colonies in the eastern portion of its range. Its disjunct distribution pattern is unusual among North America's grasses.
