Somebody else mentioned Lycopus, and this looks like one. Is it stoloniferous and fast growing, like a mint (Mentha?)

One more photo...
It seems to me that Lycopus has blooms from the leaf axils and this plant blooms at the tip of the stem.(see pic below) It *is* stoloniferous, though...I pulled one up and there was a long root with nodes on it.

There is no "salvia" fragrance in the crushed leaves.

Modern researches indicate that Salvia has shown some positive legitimate results in the laboratory research, though the concern shown by public is also true. Salvia divinorum, contains an active ingredient, Salvinorin A, which is a powerful hallucinogen that affects the brain, working exactly in the same place as morphine, and other pain killers
