Vegetative propagation is a type of asexual reproduction in plants, by which new plants are produced from the roots, stems or leaves of a parent plant. Cuttings are usually leaves with a piece of the stem attached. When placed in water, after a few days, roots begin to sprout from the cut stem. Eventually, this can be placed in soil and grown. The new plant is an exact genetic replica of the parent. Runners are another example. Sometimes, a long, sideways stem, runs aboveground and where it touches the soil, it can send roots into the ground. This is a way for many weeds to spread around the yard, and the way strawberries spread all over the garden. Another example is rhizomes, which is like a runner, but it is an underground stem that spreads in many directions. An example of reproduction with a rhizome is an iris plant. Bulbs are an example of vegetative propagation. Each plant that comes from the bulb is identical to the parent plant that produced it. Bulbs are found in onions and tulips, for example. If you cut the eye of the potato and place it in soil, with water, eventually, it will grow into another potato, but an exact replica genetically of the parent. Another example of vegetative propagation is grafting. You can take a woody plant that is potted and cut one of the stems on an angle. You can attach a stem from a different plant, cut on the same angle. Wrap the graft with tape or cover it in wax. Eventually, the conducting tissues should join together and the graft will take. This is a way for two different species of plants to grow on one tree. An example is pears, grafted onto an apple tree.
