Vegetative propagation is a mode of asexual reproduction in which new plants develop from vegetative parts of a parent plant (the root, the stem or the leaves) under appropriate conditions, without seeds. Two methods: layering and grafting. (Growing plants from stem cuttings is another.) Advantages (any two): (1) the plants bear flowers and fruits earlier than plants raised from seeds; (2) plants that have lost the capacity to produce seeds, such as banana, orange, rose and jasmine, can be propagated; (3) the new plants are genetically similar enough to the parent plant to have all its characteristics, so a desired variety is preserved.
