Good examples of plants with underground rhizomes include medicinally important ginger and turmeric and the economically damaging weeds Johnson grass, bermuda grass and purple nutsedge. The spreading stems of ferns are also rhizomes. Some plants have rhizomes that grow above ground or that sit at the soil surface including some Iris species. Rhizomes may also be referred to as creeping rootstalks, or rootstocks. A stolon is similar to a rhizome, but instead of being the main stem of the plant, which is what a rhizome is, a stolon sprouts from an existing stem and has long internodes and generates new shoots at the end. A good example of a plant that grows with stolons is strawberry.

Grass and ferns both have rhizomes, or 'horizontal stems.'
