I wish I could see the leaf shape better as I don't think it is
"Russian Sage", but one of the Lavenders. "Russian Sage" has a very
pungent "fragrance", almost offensive, whereby Lavender is a lot easier
on the olfactory senses. I do grow both and find the RS tends to be
invasive and has a very unkempt appearance. Lavender tends to stay
where it is planted, has more upright growth.
