It is a type of reproduction in which new plantlets are formed from the plants somatic or vegetative cells, buds, and organs.
Characteristics:
- It takes through vegetative parts like the root, stem, leaf, and buds.

Vegetative parts of a plant
- The vegetative portions of the plant separate from the parent body and grow into a separate daughter plant during this method of reproduction.
- Meiotic divisions are absent, and only mitotic divisions are present, because it does not include the fusing of gametes.
- Genetically, the daughter plants are identical to the parent plant.
Vegetative reproduction can occur through leaves, stems, and roots, as previously mentioned.
Vegetative propagation through leaves:
In Bryophyllum (also called sprout leaf plant), small plants grow at the leaf notches. If the leaf is buried on moist soil, the margins of the leaves develop into a new plant that resembles the parent.

Vegetative reproduction by leaf
Vegetative propagation by stem:
This method is suitable for is strawberry, rose, Champa, money plant, sugarcane, banana, cactus, rose, grapes, jasmine etc.
- In this type of propagation, the aerial weak stems of the plant tough the ground and give rise to adventitious roots and buds.
- When the parent plant's connections are removed, the offspring become independent.

Vegetative reproduction by stem
Vegetative propagation by roots:
- In plants like sweet potato, dahlia, blackberry etc., a new plant develops through tuberous roots (acts as a storage organ).
- There are buds present on these modified storage roots that can grow above the ground, and a new plant is formed.

Vegetative reproduction by roots
Bulbils:
Bulbils are flower buds that have been changed into globose in some plants. These fall to the ground and sprout into new plants.
It is seen in Agave.
