This is one of my favorite mints! It is easy to grow in full sun or partial shade. Some people claim that it is incredibly invasive; however, I have not had any problem. Of course, I also have a mint garden, so my idea of invasive is probably different from other people's idea. Nevertheless, it has not spread quite as much as some of my other mints. It does grow well in a container, too. It is edible and also has medicinal properties. I, however, love it for its fragrance, which is so different from my other mints.

Great Plant! It benefits alot of wildlife. It attrachs all sorts of wasps, bees, butterflies, and other insects. However the wasps and bees are not the stinging type i belive. Their very shiny looking, almost metalic. It likes to spread so be careful where you put it. Plus it smells awesome.
