Plant Spotting: Bulbous Bluegrass
Poa bulbosa L.
Bulbous bluegrass is a monocot perennial from Eurasia and North Africa. It was introduced to the western United States around 1915, probably as a contaminant in shipments of alfalfa seed. It was then intentionally planted as a weed and erosion control. It can now be found in disturbed and over-utilized areas, like pastures, forested areas, and along roadsides across the country. While it can be a noxious weed in many places, it can also good forage for ruminants, small mammals, and birds. Bluegrass grows in clumps up to 60 centimeters tall. Its stems are smooth and hollow, and can store water when necessary.
