Summary

Bromus squarrosus, commonly known as rough brome, is an annual grass that is native to temperate regions of Europe and Asia. It typically inhabits disturbed sites such as overgrazed pastures, fields, and road verges, where it can quickly colonize bare ground. Rough brome reaches a height of 8-24 inches with hollow, erect culms that bear four to five leaves. The leaf sheaths are pubescent, giving the plant a rough texture. It produces open, feathery panicles that are particularly noticeable at maturity during the flowering season.

Rough brome is not commonly cultivated but can be found in wildflower mixes for meadow creation or erosion control due to its ability to establish quickly in disturbed soils. It prefers full sun and can tolerate a range of soil types, from sandy to loamy, with moderate water requirements. However, its potential for invasiveness should be considered before planting, as it can spread rapidly and outcompete native vegetation. In some regions, it is regarded as a weed and may require management to prevent unwanted spread.CC BY-SA 4.0
