Have 6 plants growing. Besides keeping our cats doped up we have been making tea. We use the leaf, lemon grass, oregano and several other herbs for a nice relaxing night time brew. Chewing the root can be used as a stimulant. Very good stuff. Really getting into medicinal plants. Greenhouse is full of all kinds of cool things such as kratom, yerba mate, dragon fruit and other things. One of the coolest is sea onion. You use the leaves as band aids that has a natural antiseptic. If your into teas try growing some catnip.
