I grew spearmint in a big plant container last year. I brought the container indoors to the enclosed porch for the winter, and all the leaves turned brown so I pruned it all down. When all the leaves turned brown, I thought it died, so I stopped watering it. Then the other day, I saw that it was shooting up new leaves! Oh wow! This is a plant that just doesn't die. It is definitely a "super" plant. I'm pretty excited that new shoots are coming up. It's no wonder some people call mint "weeds" and warn not to plant it in the ground!! They don't die, and just keep coming back just like weeds. However for me, I love mint, so it's not a weed to me. I just love, love, love how crazy the plant is!
