Common Name: Sweet Woodruff
Galium odoratum — commonly called Sweet Woodruff — is a low-growing, spreading perennial groundcover valued for its delicate foliage, fragrant flowers, and ability to thrive in shade. It forms a dense carpet of bright green, whorled leaves that create a soft, textured appearance. In spring, clusters of small, star-shaped white flowers rise above the foliage, adding a light, airy effect. The foliage releases a sweet, hay-like fragrance when crushed or dried.
