The plant has few leaves, mostly at the base, and these are bristle-like. Its seeds can remain viable but dormant in the soil for several years. The seeds germinate in spring and autumn, whenever temperature and moisture conditions are favourable.
Control
Rushes tend to grow on wet soils that are also often acidic. Accordingly, drainage and liming are two good weapons for limiting their establishment and growth. Manually pulling the plant out and spot treating with glyphosate will provide effective control.
