About Sweet vernal grass

Anthoxanthum odoratum, commonly known as "Sweet vernal grass," is a low-growing perennial grass valued for its sweet, coumarin-like fragrance, which intensifies as it dries. Its delicate yellowish-green flower spikes emerge in spring and summer, adding texture and a subtle scent to naturalized meadows, wild gardens, or roadside borders. It's an excellent choice for creating a rustic ambiance and attracting pollinators.

Native range

Temperate Eurasia and North Africa.

Care tips

It prefers full sun to partial shade and adapts to a wide range of soils, as long as they are well-drained. Watering is minimal once established, as it tolerates drought well, though some moisture during dry spells encourages its growth. It does not require regular fertilization. A common mistake is planting it in very fertile or wet soils, which can lead to excessive growth and less flowering.
