Did you know?
Alpine sweet grass, like its close relatives indian sweet grass (Anthoxanthum hirtum and A. nitens) and sweet vernal grass (A. odoratum) has a sweet fragrance when cut, which is a result of the presence of coumarine. This aromatic organic compound also produces the fragrance of fresh-cut hay, and is used in perfumes.
State Ranking Justification
There are eight known extant populations and about half of these have fewer than 100 plants.
