Stolons are modified stems that grow horizontally along the ground and produce a prostrate or sprawling mass of stems growing along the ground.

Stolons occur in woody plants (red twig dogwood - Cornus stolonifera),

herbaceous perennials (bugleflower - Ajuga),

and grasses (burmuda grass - Cynodon dactylis).

Bottlebrush buckeye (Aesculus parviflora) spreads by stolons to form large patches.

Runners are specialized stolons that develop from the crown of a plant that grows horizontally along the ground and forms a new plant at the nodes.

Stolons may also produce tubers at the tips of the stolon.

This is a mechanism for moving the new propagules (tubers) away from the main crown.
