I grew this last year. So-so germination, a little bit of a drought here so had to water the garden every morning. Had 4 plants pull through and got enough flowers and small leaves to make a tincture. Did take a small blossom and bit on it and it did numb that whole side of my mouth. My husband wears dentures without any of the plastic based adhesives and likes taking a little bit of the tincture in some water and swishing in his mouth. Helps his gums stay healthy and numbs any little pain for eating. Expanding the area this summer.
