Bulgarian lavender has a deeper, more fixative scent with a herbaceous tone, while French lavender grosso has a heavier almost medicinal tone. Uses of all of the unblended lavenders are similar (anti-depressant).
“This is almost my favorite. I can only describe it as “refined” when compared with grosso. This is a matter of personal taste, and my taste leans towards Bulgarian, or for very special occasions, the California lavender.” - Susan Siemers, Owner and Founder Ceres & Co.
