Lolium multiflorum aka Annual Ryegrass

Lolium multiflorum, also known as Italian rye-grass or annual ryegrass, is a herbaceous grass native to temperate Europe. Its exact native range is unknown, but it is widely grown for silage, as a cover crop, and as an ornamental grass. However, it can become a noxious weed in arable areas and an invasive species in native habitats, as it readily naturalizes in temperate climates. It is also a host plant to wheat yellow leaf virus in Europe. Italian ryegrass is sometimes considered a subspecies of perennial ryegrass, but it differs from L. perenne in its spikelet and stem. Italian ryegrass has become a widespread weed in crops and roadsides in southern and eastern Australia, where it readily hybridizes with other ryegrasses. Hybrid ryegrass is more common than Italian ryegrass in naturalized ryegrass populations in some states. Although it is largely seen as a weed of crops and disturbed sites, Italian ryegrass is also regarded as an environmental weed in some situations. It is a potential threat to one or more vegetation communities in Victoria, where it is a common weed of plains riparian shrubby woodlands and floodplain riparian woodlands. It has also been recorded in conservation areas in the inland regions of southeastern Australia. In agricultural areas, it can become invasive in temperate climates. To control Italian ryegrass, pulling, hoeing, tilling, and digging can often take care of weed problems without the need for chemical sprays. In contrast, annual ryegrass is a super rare houseplant that requires regular watering and long-lasting, direct light to thrive. It prefers well-draining soil and may benefit from a gentle, organic fertilizer throughout the peak growing season. Annual ryegrass belongs to the Lolium genus and is native to Europe.
