Facts

Fragrant bedstraw gets its name from the vanilla scent of the dried leaves and the fact that it was formerly used to stuff mattresses. Fragrant bedstraw was used by native Americans mashed and applied to the scalp to stimulate hair growth.

Habitat

Forests, swamps, talus and rocky slopes, wetland margins (edges of wetlands)
