Definition

Meaning

A perennial Eurasian grass (Anthoxanthum odoratum) known for its sweet-smelling foliage when dried, due to coumarin content.

A plant traditionally used for scenting linen and hay, and as an indicator of old, unimproved grassland. Often associated with pastoral landscapes and traditional hay meadows.

Linguistics

Semantic Notes

The name is descriptive: 'sweet' refers to its scent, 'vernal' to its spring flowering, and 'grass' to its botanical family. It is not typically cultivated but valued in conservation for its role in creating 'scented hay'.

Dialectal Variation

British vs American Usage

Differences

The term is used in both varieties but is more common in British ecological and agricultural contexts due to the historical importance of hay meadows. In American contexts, it might be specified as a non-native species in certain regions.

Connotations

Frequency

Higher frequency in UK nature writing, conservation literature, and historical agricultural texts.

FAQ

Frequently Asked Questions

No, it is a different species (Anthoxanthum odoratum) not typically used for lawns. It is shorter and valued for its scent and ecological role in meadows.

Yes, it can be grown from seed and is suitable for wildflower meadows or naturalistic plantings, preferring poor to moderately fertile, well-drained soil.

'Vernal' comes from the Latin 'vernalis', meaning 'of the spring', because this grass flowers in spring (April-June in the Northern Hemisphere).

When fresh, it is generally safe in moderation. However, when mouldy or spoiled, the coumarin can be converted to dicoumarol, which is an anticoagulant and can be harmful to livestock.
