Taxonomy

Description

Native, perennial, cool season bunchgrass.[1]

Leaf sheaths are open, leaves are 1-2mm broad, and basally tufted.

Culms are 3-6 dm tall, topped with fluffy-appearing, congested inflorescences (4-13cm.) which form a spike-like panicle.

The spikelets are mostly 2-flowered and are borne on short pedicels with paleas shorter than the lemmas[2]

Bloom Period

May - June[2]

Distribution

Alaska south, on both sides of Cascades, to northern Mexico, east across most of North America to Atlantic.[3]

Habitat

Dry, sandy prairies; open woods; rocky slopes Dry, well-drained soils such as silts to loams to sandy loams. It has good tolerance to fire.[1]

Uses

Prairie junegrass is used as a component of native seed mixtures in revegetation of mined lands, heavy use areas and other surface disturbed lands.Prairie Junegrass acts as a early- seral species of previously water-stressed areas.[4]

Medium palatable for browsing animals and high palatability for grazing animals. Prairie junegrass is considered a fair to good forage for elk throughout the year and is desirable forage for deer and antelope in the spring and early summer.[1]
