Another structure, the rhizome, also assists in the spread and nutrient uptake of the peppermint plant.  Like the stolon, the rhizomes are a network of specialized stem parts that branch underground.  However, instead of growing upwards and forming a new plant, the rhizome burrows down into the earth, sending out roots for nutrient uptake.  Though their chief function is not reproduction, pieces of the rhizome that become detached from the main plant have the capacity to generate a brand new plant.  This technique is used most often in commercial cultivation of M. piperita. Two other well know organisms that take utilize a rhizome are the sweet potato and ginger.

In addition to its genetically predisposed complications, the peppermint plant thrives in climates that are above the 41st parallel.  As seen in the habitat page, and sadly for the residents who also live here (myself included) this region is located nowhere near the tropics.  Now, you may be asking yourself how it is that M. piperita survives subzero temperatures and several feet of annual snowfall.  The answer is quite simple; it uses the snow as a blanket to protect its rootstock (the stolons and rhizomes).  Just like the layer of ice that forms on the top of a lake insulates the still liquid water below and allows the fish to survive the winter, the snow does the same for the peppermint plants.  When temperatures begin to rise in the spring, M. piperita benefits from the snowy covering as it melts and provides plenty of water for growth and development.
