The propagation of strawberry is relying on the runners, but not the fruit. The original plant will stretch its runners horizontally, and seeking any space on the surface for them to root. Once they get into position, then they are ready to grow.
Runners do not have leaves to absorb energy. Therefore, the original plant will need to provide energy continuously, until the new plants established. This process looks like one generation keeps sending messages to another, and hope those little ones are able to grow up healthily.
