Oh, dear. Make sure you plant your mint(s) near a source of water, and in a place that is contained, or it will take over you house, your life, and your yard. I have two kinds that I planted near a downspout. You'll find that in cooking you simply have to live with different products. I actually started with four kinds of mint, and am down to three. Two are the very invasive kind, and have to live near the roof downspout. I know one is spearmint, the other I think is peppermint (ruffly edges?). I had pennyroyal there as well, because it has insect repellent properties. But then I learned it was an abortion agent, and rooted it out and killed it off. Don't want to accidently hurt anyone! I have lemon balm as well. I use all of these in my southeast asian cooking.
