What does rhizomatous mean?
Rhizomatous is a botanical adjective describing a plant that has, produces, or spreads by means of rhizomes. Rhizomes are underground stems that store nutrients and can grow both upward into new shoots and outward into roots, allowing some plants to form extensive colonies. The term is especially associated with grasses such as bamboo, but it can describe many kinds of plants. In ecological and horticultural writing, “rhizomatous” may also suggest vigorous underground spread and the ability to regenerate from fragments of the rhizome. It is more precise than simply calling such a plant invasive or aggressive, because it identifies the particular underground mechanism involved. Outside botanical contexts, the word is uncommon and is generally understood in its literal horticultural sense.
adjectiveHaving or resembling rhizomes, underground stems that can produce new shoots and roots. In botany, it describes plants whose growth and spread occur through rhizomes.

Where does rhizomatous come from?
The word is formed from “rhizome” plus the suffix “-ous,” meaning “having the nature or character of.” “Rhizome” comes through Latin from Greek rhízōma, a stem or root, ultimately from rhíza, “root.” The same Greek root appears in related botanical and biological terms. The resulting adjective has followed the modern botanical sense of plants that grow or spread through underground stems.
How rhizomatous is actually used
This is primarily a botanical term. It is usually applied to plants and their growth or spread, and it is more technical than the everyday expression “spreading through underground stems.”
Easily confused with rhizomatous
A rhizome is the underground stem itself, whereas rhizomatous describes a plant or growth form characterized by rhizomes.
