Anthoxanthum odoratum - Sweet Vernal Grass, Vanilla Grass

Sweet vernal grass is grown for the sweet scent in its leaves and flowers. It is easy to grow and will self-sow freely to fill in an area by the end of the first season. One customer planted a large area on a bank below a deck and each spring through early summer the breeze off the ocean fills the landscape with a sweet scent.

The origin of this pretty grass is Eurasia and it is grown in many parts of North America.

Some people add a few flowers to their tea!
