Bluebunch Wheatgrass
Nodding Onion

Bluebunch Wheatgrass is a native perennial bunchgrass common across prairies, foothills, and open woodlands. It has a long life span, unlike many other grasses.
This grass competes well with invasive species, has extensive root systems and is drought tolerant. It provides forage for deer, elk, bighorn sheep, and is extremely palatable by livestock. Its seeds are eaten by birds and small mammals, while its dense clumps offer nesting and shelter.

Nodding Onion is a native perennial wildflower known for its nodding clusters of flowers that range in color from white to pink to purple. The lightly scented blooms provide pollen and nectar for pollinators, especially bees, which can collect while hanging upside down, a capability most other insects lack.

The narrow, grass-like leaves of the Nodding Onion can be used as a seasoning in cooked dishes, though bulbs and raw leaves should not be eaten in large quantities. All parts of the plant have an onion-like aroma when bruised, which helps deter deer and rabbits. They can self-seed readily, so removing spent blooms helps manage their spread. Tolerant of a range of soils, including alkaline, it is well-suited for a variety of plantings, including pollinator gardens and naturalization projects.
