Poa nemoralis L.
Common Name: BLUEGRASS
Coefficient of Conservatism: *
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Ad P-Grass

Dry, often shallow sandy or rocky soil, such as forest borders and clearings, along forested trails, old homesites; rock ledges and bluffs in the Upper Peninsula.

Poa nemoralis was first collected in Ingham Co. in 1895 and is presumably an introduction from Europe as most of our collections are from disturbed, open forests. However, some of our plants, placed as P. nemoralis by their very short ligule and leafy stems, do occur on the rocks of the Lake Superior region and rock ledges and bluffs in other wild areas of the Upper Peninsula. In P. nemoralis, the tip of the longest glume equals the tip of the lemma opposite, while in P. interior, the glume is often slightly shorter.
