Grassy Weed – Annual Ryegrass

(Lolium multiflorum)

Annual Ryegrass – also referred to as Italian Ryegrass and Australian Rye – is an annual grassy weed. Lolium multiflorum is typically found growing in moist to wet soils with reasonably good drainage. Annual Ryegrass thrives throughout much of North America.

Identifying Annual Ryegrass -

Annual Ryegrass can be identified as a tufted, apple-green colored winter annual with a short ligule and broad collar. Its auricles are narrow and claw-like and its blades are long and tapered with prominent veins. The blades are very glossy on one side and rough on the other, with smooth edges. Annual Ryegrass also features sheaths that are not compressed and is yellowish-green in color at the base.

Annual Ryegrass is often used as a nurse crop or as a temporary turf to quickly fill in bare areas due to its rapid germination. It may also be used to over-seed Southern turfgrasses in the winter to provide green grass all year round.

Annual Ryegrass Control -

Its rapid germination, combined with its tolerance for low mowing heights, often allows Annual Ryegrass to become invasive in home lawns. It may even out compete desirable grasses if not properly managed.
