Until a few years ago each spring I'd buy a small pouch of this aquatic herb at south Tampa's DoBond Market and grow it in a pond or in a pot of soil in standing water. It is chopped raw atop certain Vietnamese dishes.....the flavor "changes" as you chew from minty then lemony then cumin. Interesting yet delicate. Nate just gave me a clump now in a 6 inch pot in standing water. Time to look up Vietnamese dishes again!
