Vegetative propagation is a method of asexual reproduction in plants. In this method, a vegetative part of a plant gives rise to new plants. This vegetative part which has the ability to produce new plants is called vegetative propagule. Some common vegetative propagules are runner, rhizome, sucker, tuber, offset, bulb etc. Vegetative propagation is of two types i.e. natural vegetative propagation and artificial vegetative propagation. In natural vegetative propagation, a vegetative structure detaches from the parent plant and give rise to new plants. Artificial vegetative propagation includes methods developed by horticulturists to readily develop multiple plants through vegetative propagation. 

The examples of vegetative propagation are

1. Vegetative propagation by roots: Roots of some plants can develop adventitious buds to form new plants e.g. Dalbergia, guava, poplar, Albizia, Murraya etc. Fleshy roots such as those of sweet potato, tapioca, Dahlia etc. also develop adventitious buds and form new plants. 

2. Vegetative propagation by leaves: The leaves of some plants develop buds over them. From these buds, new plants arise. E.g Bryophyllum.
