self-propagation
Natural Methods of Asexual Reproduction Natural methods of asexual reproduction include strategies that plants have developed to self-propagate. Many plantslike ginger, onion, gladioli, and dahliacontinue to grow from buds that are present on the surface of the stem. In some plants, such as the sweet potato, adventitious roots or runners can give rise to new plants Figure 32.25. In Bryophyllum and kalanchoe, the leaves have small buds on their margins. When these are detached from the plant, they grow into independent plants; or, they may start growing into independent plants if the leaf touches the soil. Some plants can be propagated through cuttings alone.
