Definition - What does Rhizome mean?
A rhizome refers to the modified stem of a plant that tends to grow horizontally instead of vertically. Rhizomes grow under the soil and new growth may occasionally sprout at different angles. Because it is found under the ground, a common misconception is that the rhizome is part of the root. However, it is actually a stem that grows beneath the surface of the ground.
Rhizomes play a crucial role in propagation and reproduction because they have the capacity to invade the space next to the parent plant, consequently encouraging the appearance of fresh new shoots.
MaximumYield explains Rhizome
In botany, there are several different types of rhizomes. For example, a type of rhizome known as rootstock is often used in plant propagation, especially when it comes to orchids, cannas, lilies of the valley, and asparagus.
Rhizome propagation is actually the most popular form of asexual reproduction in large hectares of agricultural land. Some plants, however, can form stems under the surface of the ground without necessarily forming rhizomes. Examples include tubers, runners, corms, and bulbs.
