What Is Rhizome?
Last Updated: June 2026 - Roots & Storage
Definition
A rhizome is a thick horizontal stem, usually at or below the soil surface, that stores energy and sends out roots and shoots.
Quick Facts
| Plant term | Rhizome |
| Category | Roots & Storage |
| Common example | ZZ plants grow from potato-like rhizomes that store water. |
| Care takeaway | Avoid constantly wet soil around thick rhizomes, especially in ZZ plants and snake plants. |
Why It Matters
Rhizomes store water and nutrients, help plants survive stress, and make division possible. They also affect watering: plants with fleshy rhizomes often rot if kept too wet.
How to Identify It
- ->Look for thick horizontal growth at or just below the soil surface.
- ->Rhizomes often produce both roots and shoots from the same swollen structure.
- ->In ZZ plants and snake plants, rhizomes may look like firm underground storage pieces.
Care Notes
- ->Avoid constantly wet soil around thick rhizomes, especially in ZZ plants and snake plants.
- ->Divide rhizomatous plants when the pot is crowded and each section has roots and shoots.
- ->Use well-draining mix so rhizomes get oxygen as well as moisture.
Examples
ZZ plants grow from potato-like rhizomes that store water.
Snake plants spread by underground rhizomes and can crack crowded pots.
Many calatheas grow from rhizomes and can be divided carefully.
Rhizome vs. Tuber vs. Corm
All three store energy, but their structure and propagation behavior differ.
| Structure | What It Is | Houseplant Example |
|---|---|---|
| Rhizome | Horizontal modified stem that sends out roots and shoots | ZZ plant, snake plant, calathea |
| Tuber | Swollen storage structure with growth points | Cyclamen, string of hearts tubers |
| Corm | Short solid underground stem | Alocasia corms |

Frequently Asked Questions
Botanically, a rhizome is a modified stem, not a root. It can grow roots from itself, which is why the terms are often confused.
Yes. Many rhizomatous plants can be divided if each piece has healthy roots and at least one growing point.
