Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
It is drought tolerant, growing in coastal sage scrub, chaparral, the California oak woodlands of southern oak woodland and foothill woodland, and Joshua tree woodlands, rarely in wetlands. It often hybridizes with Leymus triticoides, producing the common hybrid grass Leymus x multiflorus. The plant's leaves and seeds are often consumed by both ...
The primary species found worldwide and used both for lawns and as a forage crop is perennial ryegrass (Lolium perenne). Like many cool-season grasses of the Poaceae, it harbors a symbiotic fungal endophyte, either Epichloë or its close relative Neotyphodium, both of which are members of the fungal family Clavicipitaceae.

The Sierra Nevada are home to half of the vascular plant species of California, with 400 species that are endemic to the region. [16] Like many mountain ranges, the plant communities of the Sierra group into biotic zones by altitude, because of the increasingly harsh climate as elevation increases. [ 19 ]
Of California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. [4] This botanical diversity stems not only from the size of the state, but also its diverse topographies , climates, and soils (e.g. serpentine outcrops ).
It started on December 11, 2011, and ended on March 5, 2019. The most intense period captured on the drought monitor was on the week of July 29, 2014. It showed that 58.41% of California's land was affected by a drought. In 2014–2015, farm-related losses in California totaled $5 billion and 20,000 farmers also lost their jobs. [citation needed]
It is usually a smaller plant than ssp. mollis. [4] The two subspecies are otherwise hard to tell apart, even when growing sympatrically . The most reliable character to use to distinguish them is the type of hairs on the glumes and lemmas ; [ 5 ] ssp. villosissimus has long, soft, sometimes shaggy hairs ( villous ), while ssp. mollis has fine ...
