Achnatherum calamagrostis or silver spike grass

This member of the Gramineae family (now called Poaceae) forms large clumps on stony, dry and sunny ground. It grows in abundance here on the track embankment, taking advantage of the sunlight allowed through by the break in the forest. Its inflorescences reflecting silvery-gold glints are made up of flowerets with long edges. They create a very misty effect in the late summer when the plant is mature, forming large shimmering bouquets in the evening sunlight. .
