Anthoxanthum odoratum Sweet Vernal-grass

Anthoxanthum odoratum, Sweet Vernal-grass, is a very common perennial grass which is found in all sorts of grassland and meadow habitats in Britain. It is one of the first grasses to flower in Spring and, as a result of its high coumarin content, it gives rise to a distinct smell of new-mown hay when it is freshly cut (or crushed), hence its common name. Individual plants appear to be relatively short-lived, so its success is dependent on good seed production. Furthermore, it is self-incompatible, so it relies on massive pollen production and cross fertilisation to produce seed and it is probably one of the most important contributors to hay fever in early Summer. It common and widespread in West Galmorgan.
