Advantages of vegetative propagation:
  1. For propagation of plants that produce little or no viable seeds.
  2. Many fruits are cross pollinated, so to provide consistent quality without variation vegetative propagation is preferred.
  3. Most often easier, rapid and more economical method.
  4. Flowering period is short compared to seed propagated plants.
  5. Method of choice in propagating plants in unfavorable environmental condition.
Jasmine and banana are grown by this process.
