About This Grass
An upright, tall, cool-season bunchgrass growing up to 20 to 40 inches tall when mature. It has a light green to gray-green color and produces distinct, dense, cylindrical, spike-like panicles (phytomers resembling tiny cylinders or cat's tails) at maturity.
Blade Characteristics
Blades are medium-width (3-8 mm), flat, smooth to slightly scabrous, pointed at the tips, and light green or blue-green. Vernation is rolled in the bud. The ligule is membranous, obtuse, and prominent; auricles are absent.
Root System
Shallow, fibrous root system with no significant rhizomes or stolons. Relies heavily on its bulbous corms at the base for energy storage and survival during adverse conditions. Establishes easily from seed but lacks dense sod-forming traits.
Growing Information
Origin Region
Native to Europe, temperate Asia, and northwestern Africa; widely naturalized and cultivated across North America and temperate regions globally.
Growth Habit
Bunch-type (clump-forming) with shallow root systems and swollen, bulb-like basal internodes.
Sunlight & Water Needs
Requires full sun and moderate to high moisture levels. It has poor drought tolerance due to shallow roots but excellent cold hardiness.
Mowing & Maintenance
Maintained as a forage or hay crop rather than a traditional lawn. Cut at heights of 3 to 4 inches for hay production. Requires moderate to high fertility (especially nitrogen) for optimal yield.
Special Characteristics
Highly palatable livestock feed, especially for horses and cattle when harvested as hay. Moderate wear tolerance as a bunchgrass; poor persistence under heavy, continuous grazing.
Ecological Information
Introduced species in North America widely used for hay and pasture blends with legumes like alfalfa or red clover. Provides nesting cover for ground-nesting birds and helps stabilize soil in agricultural settings.
