In temperate deciduous forests, most of the small flowers that grow on the forest floor must complete their life cycle quickly before tree leaves shade out most of the light. Many of these plants reproduce asexually by runners
What advantages does this have for such plants?
The environment that the offspring occupy is the same as that of the parents, so the offspring are likely to do well if they are identical to the parents. If the flowers do not get pollinated during their brief life span, the plant is still able to reproduce. Also, the offspring get nutrition from the parent.
