I found a small plastic bag with one pot’s worth of something labeled “Grandma’s Garden” in one of the cupboards in my parents’ house. In a Christmas themed tin, of all places. If I recall correctly, we got it from a little tea shop in Urbana-Champaign when we visited my sister, so that must have been at /least/ three years ago…
It’s obviously not the freshest, but it still tasted all right — like those Celestial Seasonings fruit zingers, but better, with a better balance of the acidity and sweetness. Not my favorite, but take that with a grain of salt, since I’m not even /entirely/ sure this is the same tea we’re talking about… =P
