Sweetscented Bedstraw
This mat-forming plant produces whorls of 6 to 8 fragrant leaves, which smell like freshly mowed hay. It is listed as being absent from Connecticut, but apparently it is not since I found it in Connecticut.
The sweet scent of this plant is derived from coumarin. This smell increases with wilting and the dried plant is used in potpourri, as a moth deterrent, and as a flavoring in many beverages in in Germany.

"Galium odoratum", the sweet woodruff or sweetscented bedstraw, is a flowering perennial plant in the family Rubiaceae, native to much of Europe from Spain and Ireland to Russia, as well as Western Siberia, Turkey, Iran, the Caucasus, China and Japan.
