I've been wondering about this for a while. I had a peppermint plant a while back and some of its roots had gotten accidentally cut off. Though the peppermint plant did have more than enough roots to keep growing, I can't help wondering something. If I had saved those cut off roots, not exposed them to any light, and planted them under the soil (taking care of them like I would with a growing plant), would they have been able to grow into a whole new peppermint plant or not? If not, then why?
Your peppermint probably would have sprouted a plant from the roots if they were large enough. Different plants have different root systems and react differently when separated from the green leaves above ground that manufacture food to feed the roots. Mints tend to sprout easily from roots alone. Newt
