Vegetative propagation is a type of asexual reproduction in plants. There are different methods of vegetative propagation like cutting, budding, grafting, tissue culture etc. Different types of roots and shoots such as rhizome, bulb, tuber are capable of vegetative propagation. Plants like ginger reproduce asexually by forming rhizome which is a modified stem. Plants like onion, tulips reproduce asexually by forming bulbs. Plants like potatoes, dahlia reproduce asexually by forming tubers. Algae such as spirogyra shows vegetative reproduction by fragmentation method. Vegetative propagation in sweet potatoes, bryophyllum, banana, etc is done by leaf buds.
