Inflorescence is more or less one-sided, generally appressed to rachis to ascending. The spikelet is generally more or less cylindrical, the callus hairless or with a small ring of hairs. Lemma weakly keeled to rounded. 
From Southeastern Alaska across southern Canada, although more sporadically east of the Rockies. Throughout the western states of the US and Great Plains, infrequently in New Mexico and Arizona.
It grows well in rich soils but most commonly grows in rocky, shallow, or sandy soils.
Documentation of Newe use of seeds as food.
Poa secunda greens up in the spring earlier than other grasses, and is a desirable forage for grazing animals, and increases under grazing pressure. It regenerates after fire, and because of early growth, is often dormant when fires occur.
Reproduces by tillering and by seed. P. secunda is wind-pollinated and self-fertile, and can also produce viable seeds without pollination.
