When I lived in Hawaii, I had a kaffir lime tree in a pot. Oh, how I miss that flavor. In Florida I grew lemon grass in a corner of the yard. That one was funny. We'd gone to a Thai restaurant in Orlando, and I looked down at the stuff growing by the sidewalk, and saw ... lemongrass. We were leaving, and I just was going to grab one or two stalks to start a plant at home. I got caught, but do what I always do when I'm caught out in a transgression --- apologise and explain. The owner's wife was thrilled that I even knew what I was doing, and gave me a good size cutting, and I had a ton of lemongrass for the rest of the 6 years we lived there. I'd like to try growing both (lemongrass and Kaffir) in pots, and someone gave me a source a few months back, but I can't find where I saved it (the story of my life). I use lemon balm or verbena (the latter is better, but haven't found a plant lately) in the summers, but lime skin in the winter, to give the zip of lemongrass/kaffir lime. Not the same, but ya gotta do what ya gotta do.
