rotes Straußgras

Cloud grass refers to ornamental and native grasses in the genus Agrostis (family Poaceae), particularly Agrostis nebulosa, a delicate annual grass native to the Iberian Peninsula and northwestern Africa that produces large, airy, cloud-like panicles of minute spikelets on extremely fine, hair-like branches. The panicle's ethereal, misty appearance in mass gives the plant its evocative common name. It grows in dry, sandy soils and disturbed ground, completing its life cycle quickly in spring before summer drought conditions. Agrostis nebulosa is widely cultivated as an ornamental grass for cut flower arrangements and dried flower compositions, where its delicate panicles add texture and movement to floral displays. The genus Agrostis, bent grasses, encompasses dozens of perennial and annual species distributed across cool temperate and alpine zones worldwide, including the fine-leaved bent grasses used in golf greens and lawns for their dense, low-growing turf. Many Agrostis species are characteristic of acidic, nutrient-poor soils in heathlands, moorlands, and montane grasslands across Europe and North America.
