Smooth brome is native to northern Europe and Asia. It was introduced into the United States in 1884 and is now widely distributed. It is best adapted to regions of moderate rainfall and moderate to cool summer temperatures. The plant is a long-lived perennial with creeping rhizomes. It forms a dense sod. Leaf blades are smooth, up to 12 inches long and 0.5 inch wide. The flower head is a panicle, 6 to 8 inches long. The root system is strong and interlaced, making the plant excellent for erosion control. Smooth brome is among the best of the pasture and hay grasses, being both highly palatable and nutritious.

Two types of smooth brome are recognized. "Southern" type came originally from Europe and is best suited to the corn belt and adjacent plains areas "Northern" type, originally from Siberia, is adapted to the Northern Plains and adjacent Canada areas.
