In plants such as Bryophyllum (also known as "mother of thousands") or the piggyback plant, the leaf supports development of a tiny shoot buds. These buds may begin to form roots at their base. As these shoots break off from the original leaf, they fall onto the ground and take root.
Cytokinins accumulating at the leaf margins stimulate cell division in the notches to produce these adventitious shoots.
Natural Vegetative Propagation
--Scaly Bulbs

For plants such as onions, garlic, tulip, daffodil, and hyacinth, the bulb is the unit of vegetative propagation. The stem is shortened down to a disc, often called the basal plate from which roots arise around the edge. The leaf bases are attached to the upper surface of the stem. The axillary buds always found at the node (where the leaves attach) can develop into new bulbs in subsequent years.
Thus, if you plant one daffodil bulb, a few years later you will have several bulbs in that place competing with each other for nutrients, water, and sun exposure. The flowering may be reduced as years go by unless the gardener digs up the competing bulbs and separates them in late summer. Sometimes you will discover that one onion is really "two" bulbs when you look inside.

Onion bulb, Mint s*cker, Bryophyllum: leaves, Dahlia: Tuber
Explanation:
- Vegetative reproduction is a fast reproductive phase where there is no union of the gametes.
- There are different non reproductive organs which help in in vegetative reproduction.
- In case of bryophyllum a new plant grows from leaf. These leave buds are present on the edges of the leaf. For mint, it is the s*cker.
- The s*cker is a non-green part of the stem which can lead to growth of an adult plant. In onion there are bulbs present for vegetative reproduction.
- Tubers can be seen growing from the stems of a Dahlia plant through which vegetative reproduction takes place.
