Spearmint or Garden mint has long been used by humans in drinks and garnishes and chutneys because of its characteristic menthol aroma. It uses underground runners to propagate so is best cultivated in a container instead of in the ground because it has a tendency to easily grow wild. My first experience with 'mint gone wild' was a long long time ago at a cabin in the Himalayas. We were there on a family camping trip and there was a fresh water spring in the back yard with the freshest, most refreshing water. My aunt who was with us discovered that a few hundred years upstream there was a huge patch of 'mint gone wild'. As the babbling brook ran through the mint leaves, the mint imparted its freshness to the water. Here's a picture from that camping trip - with my aunt on the left :) !! It was a long time ago but every time I eat a mint flavored drink, I remember Badi-Ma and that trip to Har-ki-doon!!
