BRAINCAKEVegetative Propagation
Vegetative propagation is the natural production of new plants from structures of the parent plant, without seeds. The new plants are clones. Common structures include:
• Runners (stolons): horizontal stems that grow along the surface of the ground. Where a node touches the soil, roots and a new plant form. Example: strawberry.
• Rhizomes: horizontal underground stems that spread and produce new shoots. Examples: marram grass, bamboo and couch grass.
• Bulbs: short underground stems surrounded by fleshy leaf bases that store food. New bulbs develop from lateral buds. Examples: onion and daffodil.
• Corms: swollen underground stem bases that store food. Example: crocus.
