Quaking- grass

Quaking-grass or briza media is a plant in the family of upright Poaceae and can reach a height of up to 80 cm. The leaves are 2 to 5 mm wide. The heart-shaped hanging spikelets are coloured purple, changing to yellow as they mature. They tremble in the slightest breeze, hence the name. This very common grass is found in meadows and dry grasslands.
