Vegetative reproduction 8 Runners - strawberry Runners Plants such as the strawberry have a very short stem, called a rootstock , with thin scale leaves. Foliage leaves and flowers grow from the buds in the axils of the scale leaves. Some of the lower buds produce shoots which grow horizontally over the surface of the ground and bear scale leaves and buds.
