Description
Densely tufted perennial herb. Leaf sheaths are nearly open, generally truncate to acuminate. Variable structure in terms of stiffness and margin flatness. 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. [2]
Bloom Period
April-July[3]
Distribution
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.[4]
Habitat
Sagebrush deserts, mountain meadows, open forest, lower alpine slopes, saline wetlands, chaparral, prairies.[4][5]
It grows well in rich soils but most commonly grows in rocky, shallow, or sandy soils.[4]
Uses
Documentation of Newe use of seeds as food.[6]
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.[4]
Propagation
Reproduces by tillering and by seed. P. secunda is wind-pollinated and self-fertile, and can also produce viable seeds without pollination.[4]
