About offset

In botany and horticulture, an offset is a small, virtually complete daughter plant that has been naturally and asexually produced on the mother plant. They are clones, meaning that they are genetically identical to the mother plant. They can divide mitotically. In the plant nursery business and gardens, they are detached and grown in order to produce new plants. This is a cheap and simple process for those plants that readily produce offsets as it does not usually require specialist materials and equipment.
