Sweet Vanilla Grass Seeds

Sweet Vanilla Grass is a charming ornamental grass treasured for its delicate appearance and remarkable fragrance. Native to Europe, Asia, and parts of North Africa, this graceful grass has naturalized across much of North America and has been appreciated for centuries for its sweet vanilla-like scent.
