If you ever get a Bpal that you sniff in the jar and don't like, I must say you REALLY still have to try it on your skin before wisking it away to a swap pile. Smelling this in an Imp I really was wondering what I was thinking when I ordered it. It smelled like nail polish remover.
But after it dried a bit, it does smell a lot better. But I really can't give a description of "hay" or "grass" because it smells exactly like one of Crayola's Magic Scent crayons. It might have been the "Lumber" or "Daffodil" crayon. I can't be sure because it's been about 20 years since I've smelled them.
