Stolon

/ˈstoʊlɑn/

Definition

Stolon refers to a slender, horizontal stem that grows at or just above the soil surface and can produce roots and new shoots at its nodes, the points where leaves or buds attach. It is a vegetative spread structure used by some plants for asexual reproduction and colony formation. Unlike a rhizome, which usually grows underground, a stolon runs along the surface; strawberry runners are a familiar example.

Function in Plants

  • Clonal spread: A stolon lets a plant colonize nearby ground by forming new plantlets at nodes, which supports quick local spread without relying only on seed production.
  • Resource connection: While attached, daughter plants can receive water, sugars, and nutrients from the parent, improving establishment until they can function more independently.
  • Useful distinction: In botany and plant identification, stolon is often contrasted with a rhizome: a stolon usually grows along or just above the soil surface, while a rhizome grows below ground.
  • Propagation value: Gardeners and growers can use naturally rooted sections to propagate certain plants, including strawberry and many turf grasses, with relatively little stress to the new plant.
