Natural vegetative propagation, also known as asexual reproduction or vegetative reproduction, is a process by which plants reproduce without involving the formation and fusion of male and female gametes (sexual reproduction). Instead, new plants are generated from the vegetative parts of the parent plant, such as stems, roots, and leaves. This method of propagation allows plants to produce genetically identical offspring, essentially clones of the parent plant.

There are several methods of natural vegetative propagation:

Stolons or Runners: Some plants produce horizontal stems, called stolons or runners, that grow along the ground. At certain points along the stolon, new plantlets develop and take root when they come into contact with the soil. Examples include strawberries and some grasses.

Rhizomes: Rhizomes are underground horizontal stems that can give rise to new shoots and roots. They allow plants to spread laterally and colonize new areas. Examples of plants that propagate through rhizomes include bamboo and ginger.

Bulbs: Bulbs are modified underground stems that consist of layers of fleshy leaves surrounding a central bud. These buds can give rise to new shoots and roots. Examples of bulb-propagated plants include onions and tulips.

Corms: Corms are similar to bulbs but lack the fleshy leaves. Instead, they have a solid structure, and new shoots develop from buds on the top of the corm. Gladiolus is an example of a plant propagated through corms.

Tubers: Tubers are enlarged underground storage stems that contain nutrients. They can produce new plants through the growth of buds or "eyes." Potatoes are a well-known example of tuber-propagated plants.
