 In horticulture, a "cutting" is a branch that has been cut off from a mother plant below an internode and then rooted, often with the help of a rooting liquid or powder containing hormones.When a full root has formed and leaves begin to sprout anew, the clone is a self-sufficient plant, genetically identical.Examples include cuttings from the stems of blackberries ("Rubus occidentalis"), African violets ("Saintpaulia"), verbenas ("Verbena") to produce new plants.
