Description from Great Garden Plants
Galium or Sweet Woodruff is a durable deer proof shade loving groundcover providing handsome leaves all season.
Sweet Woodruff is not shy about vigor. It tends to weave through the garden easily choking out pesky weeds. Excellent forcontrolling erosion on steep shaded banks and beneath trees and shrubs (especially Walnut Trees) where other shade groundcovers fail.
Galium has aromatic evergreen to semi-evergreen leaves all season. The crushed leaves emit a fragrance of freshly mown hay and when dried, lends fragrance to linens, sachets, & potpourris.
In spring, clusters of small white star shaped blooms adorn the handsome leaves.
Galium is best in a shaded site with moisture retentive soil that does not dry out. Give it a site where it is at home weaving through the garden
