Step-by-step explanation:
Strawberry plants can reproduce several ways. A strawberry plant's main stem is called a crown. This crown produces spirals of leaves, runners, and flowers. The flowers become the strawberries that we love to eat. When days are long and warm, the plant produces runners. Runners are offshoots of the parent plant, sometimes called stolons. These runners are stems growing out from the crown along the ground. The runners grow roots and along the runner, "daughter plants" can develop. Most commercial strawberry growers use runners to produce new plants.
