Italian Ryegrass (Lolium multiflorum)

Cool Season Biennial

Italian Ryegrass is a short lived biennial bunchgrass. It can grow quickly if moisture is not limiting. It has a dense shallow root system so the drought tolerance is low. Even though it is a biennial, it will rarely overwinter in most of the prairies. High moisture and short periods of flooding is generally not an issue. Salinity tolerance is rated as moderate. Seedlings are relatively easy to establish, and the plants can be quite competitive in the first year.
