A stolon is a horizontal connnection between organisms. In plants, these are stems that grow at the soil surface or just below, and are also known as runner. We can see these in weeds, strawberries,  grasses, lily of the valley and others and it is a propagation strategy allowing plants to spread out from one main plant and survive during times that are not so advantageous until the next season. A stolon sprouts from an existing stem. A rhizome is a root-like stem, which is the main stem,  that can grow horizontally or other directions underground. A rhizome is the stem of a plant underground that sends out roots and shoots from its nodes.  An example is a ginger plant, an iris, canna lily, and others. When using vegetative propagation, the rhizomes can be separated and new plants will grow.
