Origin:
Introduced from Europe, and now found widely in the western United States.
Biology:
A perennial grass that grows from basal bulbs, forming large flower spikes in the spring. This grass has become a problem in pastures, grain crops, roadsides and landscaped areas
Identification:
Most distinctive are the large garlic-like bulbs underground at the base of mature plants. Each bulb gives rise to several long, thin stems that terminate in the flower clusters. Mature plants may be up to 2 feet tall. Seed heads also are quite distinctive, looking much like tiny bulbs arranged in separated clusters along the spike. They are teardrop shaped and have a purple base and a long, pointed awn. Flower spikes may be several inches long.
Characteristicts Important to Control:
Winter germination of seeds or re-growth from the bulb. Highly tolerant of dry, compacted soils.
