Wren is my husband's favorite of the spring salts. He loves woodsy scents and said that this smells like a meadow next to a forest. I think that it smells like a mix of sweet wildflowers (I thought sugared lavender, but I see there's no lavender listed), meadow grass, and hints of wood and trees. It's a very relaxing, natural fragrance, and it's much smoother than I was expecting. I was a little scared when I first smelled these in the jar, because Wren has an aggressive, sharp, almost smoky, sour citrus tone to it, but the fragrance really sweetens and mellows in the water.
Very strong. I only used about 1/6 of the jar and had tons of fragrance (and our bath tub is a huge, two person soaker tub).
