Anisantha tectorum, also known as Bromus tectorum or downy brome, is a winter annual grass native to the Mediterranean region, including Europe, southwestern Asia, and northern Africa. It typically grows to a height of 16-35 inches (40-90 cm) with smooth, slender stems and soft, hairy leaves. The inflorescence is a nodding panicle, with each spikelet containing several flowers that can vary in color from green to purplish. Downy brome is particularly noted for its ability to thrive in a variety of soil types, although it prefers sandy or loamy soils with good drainage. It is a pioneer species that quickly colonizes disturbed sites, which can lead to increased fire frequency and altered soil properties, threatening native plant communities.

Downy brome is often used for erosion control and as forage for livestock, although its nutritional value decreases rapidly after flowering. In cultivation, it requires minimal care, growing well in full sun to part shade and in a range of soil conditions. However, due to its invasive nature, it is not recommended for ornamental use and should be managed carefully to prevent spread. Gardeners should be aware of its potential to become weedy and its ability to outcompete native vegetation.CC BY-SA 4.0
