Columbia Needlegrass

Achnatherum nelsonii subsp. nelsonii

Overview

Columbia Needlegrass (Achnatherum nelsonii subsp. nelsonii) is a rhizomatous perennial native to western North America. It is a dominant bunchgrass found in areas from hot, dry climates to high mountain meadows. The graceful light yellow seed heads with their graceful arching stems are easily distinguished from other grasses. It has a deep and extensive root system that anchors the soil and helps to keep out invasive species from encroaching. It is very important for providing food and shelter to various types of wildlife. This cool season grass is an excellent choice for areas that need erosion control and for providing a lush, consistent look.
