Perennial rye-grass is a tough native grass that can be found on roadside verges, rough pastures and waste ground; it was once the most commonly sown grass in leys (fields used for grazing livestock) and is now often used for reseeding grasslands. It flowers from May through summer, and can vary from being an annual plant to being very persistent year after year.

Perennial rye-grass has green stems and narrow, blade-like leaves. The spikelets, which hold the flowers, are attached to the stem in an alternating pattern. Perennial Rye-grass grows in clumps and has fibrous roots.
