Agropyron repens

Agropyron repens, commonly known as couch grass or quackgrass, is a type of perennial grass that is native to most of Europe, Asia, the Arctic biome, and northwest Africa. It is also present in North America as an invasive species.

Description

Agropyron repens grows in clusters, with stems that can reach up to 100 cm in height. The leaves are flat and linear, measuring up to 40 cm long and 1 cm wide. The plant's inflorescence is a spike that can be 3 to 16 cm long, with spikelets that are 1 to 2 cm long and 3 to 5 mm wide.

Habitat and Distribution

Agropyron repens is a hardy plant that can grow in a wide range of conditions, although it prefers sandy or loamy soils. It can grow in both light (sandy) and medium (loamy) soils, and can tolerate drought conditions. It is also capable of growing in heavily polluted areas, such as mine spoil heaps.

Uses

Agropyron repens has been used in traditional medicine for its diuretic and anti-inflammatory properties. It has also been used as a forage plant for livestock, although its nutritional value is relatively low compared to other forage grasses.

Control

Control of Agropyron repens can be challenging due to its extensive rhizome system. Methods of control include ploughing and the use of herbicides.
