mint is one of my favorite things to grow - its delicious! in the summer, i take a few mint leaves and a slice of lime and stick them in a water bottle and pop it in the freezer. it's a great refreshing drink in the summer and stays cold with the "ice cube" core.
but be warned - if you're growing mint outside, it will spread EVERYWHERE! It grows great in a container, but will spread like wild fire outside. I just bought a few new plants this summer, some for container gardening and some to plant around the coop. It's a great plant, but don't plant it near other things...it has a tendency to overtake and kill the other plants.
