sucker

"Suckering" refers to the natural or human-induced formation of a new stem and root system from a plant's bud. This process is a form of asexual reproduction, allowing plants to regenerate and create new individuals with identical characteristics.1

Plants like raspberries, forsythia, and lilacs are known to spread through suckers. In horticulture, suckering is a valuable technique for reproducing desirable plant varieties without significant genetic variation.1

The shoot system of plants typically branches from leaf axils, but adventitious buds can also form on older stem or root parts, leading to suckers. These adventitious shoots can arise from modified roots, as seen in the propagation of sweet potatoes and dahlias.23
