Aira

Aira caryophyllea is an annual grass indigenous to the British Isles, creating compact clumps that can reach heights of up to 30 cm. Its leaves are thin and thread-like, contributing to its delicate appearance. From late spring to mid-summer, it produces loose clusters of silvery spikelets, which may occasionally have a hint of purple.
