When most people think about root vegetables, recognizable favorites like potatoes, carrots, onions, and so on are usually the first things that come to mind. However, the variety and utility of root vegetables in nature is much broader than just these common standbys. In Missouri alone, there are many species of plants whose roots have been used by humans- for food and otherwise- throughout history. From the distant past to modern times, roots native to Missouri have seen a wide array of agricultural, medicinal, and even scientific uses. The roots that can be found in Missouri serve purposes from food to spice to muscle medication and soda flavoring, even seeing some use towards things such as cancer remedies.
Introduction
What is a Root?
First, it is useful to understand what precisely constitutes a root. Roots are – usually underground – plant structures, and are different from plant stems in several key ways. First, they do not have leaves and the associated anatomy.¹ Their function is, generally, to provide a solid anchor for the aboveground portion of the plant and to transport water and nutrients up into the stem.¹ That a portion of a plant is underground does not necessarily mean it is a root; roots possess root caps and their branches radiate from internal tissue, not buds.¹ This distinction is actually important: that onions come to mind at the thought of a root is a misconception; they are specialized flowers – bulbs – not root formations.
A Brief Explanation of Roots
Root systems vary widely between different species of plants. Generally speaking, plants will either possess fibrous roots or a taproot.²⁸ Fibrous roots are thinner systems of roots that spread through the ground, securing the plant through surface area.²⁸ These types of roots are ecologically important, as certain fibrous-rooting plants help to secure soil from erosion.²⁸ Conversely, taproots are thick roots that burrow down deep into the soil, with comparatively fewer offshoots branching out into the ground around the plant.²⁸
Almost all root systems make use of mycorrhizae systems.²⁸ This is, in effect, a symiosis between the plant’s root system and a fungus wherein the plant provides the fungus with resources and nutrients – mostly sugar – and the fungus provides the plant with greater amounts of water and nutrients from the soil.²⁸
Root networks make use of xylem tissue to transport water from the ground into the stem and other areas of the plant.²⁸ In effect, xylem is vascular tissue specialized for material transport.²⁸
The Roots of Missouri
On Taxonomy
A taxonomic discussion of the roots of Missouri would not be incredibly productive, because each root plant has its own entirely different taxonomic classification; this article focuses on a specific trait shared by many plants rather than on a specific taxon. Needless to say, all of the following species belong to the Plantae Kingdom, but beyond that there is a great amount of variety from Division down to Species.
On Foraging – A Brief Warning
This guide lists several types of edible root plants that grow in Missouri. Despite the fact that they are edible, the author does not encourage or endorse the consumption of these plants. If you do decide to forage for roots to eat, use extreme caution and identify the plants carefully.

Medicinal Roots
Full List, Alphabetical
American Ginseng (Panax quinquefolius)
Habitat
American ginseng can primarily be found in the American Midwest, though it also grows in certain provinces of Eastern Canada.² It grows in deciduous forests, primarily in rich soil on North-or-East-facing hills.² ³
Uses
American ginseng has seen a long history of use as a medicinal root. It was harvested by Native Americans for its medicinal properties, and is now used as an ingredient in some Asian herbal medicines.² Ginseng is believed by some to have medicinal value as a panacea/cureall; though there has been much debate over its legitimacy, certain modern studies have pointed towards the efficacy of ginseng being real.⁴ As a result of this, American ginseng is frequently harvested in the United States for export.² The vast majority of this is exported to China.²
American ginseng is usually consumed powedered with food, or as a tea.⁴
Conservation
American ginseng is considered to be a vulnerable plant, and is protected by certain regulations under CITES – and therefore the federal govrnment.⁴ Ginseng may only be harvested if it is older than five years at least, and certain states require licenses and mandate set harvesting periods throughout the year.⁴
Identification

The roots can be boiled into a concentrated liquid which can be used to make a beverage semblant of root beer.¹⁸ ¹⁹Identification
There are eight varieties of smilax in Missouri, which are incredibly difficult to distinguish between.¹⁸ Interestingly, between these varieties, there are smilax plants that have woody stems as opposed to herbacious stems, an unusual trait for a monocot plant.¹⁸ According to the MDC, there are three main identifiers for smilax:- White-waxy texture on the underside of leaves ¹⁸
- Stout, round stems ¹⁸
- Frequent spines on older stems ¹⁸
