A stolon, commonly referred to as a runner, is an aerial shoot from a plant with the ability to produce adventitious roots and new offshoots of the same plant.

The complex formed by a mother plant and all its offshoot connected by stolons are considered to form a single individual. A stolon is a plant propagation strategy akin to a rhizome.

Note that some species of crawling plants can also sprout adventitious roots, but these are not considered stoloniferous : a stolon is sprouted from an existing stem.

Examples of plants that extend through stolons include some species from the genera Argentina, Cynodon, Fragaria (strawberry), and Hieracium.

In potatoes, the stolons start to grow within 10 days of plants emerging above ground, with tubers usually beginning to form on the end of the stolons.

In mycology, a stolon is defined as an occasionally septate hyphae, which connect sporangiophores together. Rootlike structures called rhizoids may appear on the stolon as well, anchoring the hyphae to the substrate.
