Bromus diandrus, commonly known as great brome and ripgut brome, is an annual grass species with a notable presence in various environments.

Seeds of ripgut brome can contaminate the wool, pelt, and carcasses of animals.
The long, stiff awns of mature ripgut brome seeds can cause injury to eyes and potentially become lodged in fur.

The long, stiff awns of mature ripgut brome seeds could pose a potential hazard.

Native to the Mediterranean region, Europe, northern Africa, and western Asia.
Widely introduced elsewhere, including Oregon (west of the Cascade Mountains, along roadsides and in waste places) and the South Island of New Zealand.
Frequently infests coastal dunes and grasslands.

Ripgut brome is one of the many European annual grass species that have displaced a large portion of the native grassland.
Considered an exotic and invasive species in some regions.

Annual grass that typically grows to 6-31 inches (15-80 centimeters) tall.
Leaves are generally soft-hairy, with blades 0.07-0.27 inches (2-7 millimeters) wide.
Loosely cespitose or tufted growth habit.
Fibrous rooting system.
Produces many seeds with a short lifespan of 1-2 years.
Has large seed structures with long awns.

Ripgut brome has a quantitative response to vernalization in relation to flowering. Cold treatment can shorten the time to flowering.
Some populations show strong inhibition of seed germination when exposed to light.
