Detailed explanation-1: -Runners and stolons are surface stems characteristic of such plants as strawberries; new plants may form on the runner or stolon as it spreads along the ground. Many of the most prolific weeds have runners or stolons by which they propagate asexually.

Detailed explanation-2: -Stolons are stems that run almost parallel to the ground, or just below the surface, and can give rise to new plants at the nodes. Runners are a type of stolon that runs above the ground and produces new clone plants at nodes at varying intervals: strawberries are an example.

Detailed explanation-3: -Note: Runner is a type of subaerial stem modification usually found in the grasses and given examples as spider grass, peppermint, strawberries and Bermuda grass. Modified plants such as underground stems that derived from the stem tissues under the soil surface.

Detailed explanation-4: -Runners and daughter plants Strawberry plants reproduce through stolons or “runners.” Runners extend out several inches from the crown, take root in the soil, and produce new plants called “daughter plants.”
