[Epicene]

I've been growing it a long time. Really, just find some seeds that are clearly spearmint, and it'll grow. It's easy past that. Yes, it does take over, but you can easily grow it in a container or confine it to a bordered or raised bed outside. I just make sure to get it into my diet whenever I can, and that seems to work. For me, there seems to be a huge amount of potency in easing fresh, wet leaves though. I'm not sure how many of the active ingredients are lost in drying and making tea, but I'll eat the leaves, and it has a far stronger effect than the same amount in tea.
