What Is the Meaning of “Horticulture?”

Horticulture is, at the most basic level, the science or art of cultivating fruits, vegetables, flowers, or ornamental plants. Etymologically, the term can be broken down into two Latin words: hortus (meaning “garden”) and cultus (which means “tilling”). Master Gardeners are well-versed in this field, but its full definition actually extends beyond what we would normally think of as gardening or agriculture.
The corresponding adjective to this noun is “horticultural.” Meanwhile, if you are someone who works in this field, then you are said to be a “horticulturist.”

The Five Sub-Fields of Horticulture

As Professor William L. George explains in his definition, horticulture must be broken down into five distinct disciplines:
> Floriculture

> Landscape horticulture

> Olericulture

> Pomology

> Post-harvest physiology

Floriculture pertains to producing and marketing flowers. Think of the wholesale businesses from whom florists buy flowers to sell in arrangements to retail customers. If you have ever received a floral arrangement as a holiday gift, then you can thank this branch of horticulture (as well as the giver of the gift, of course).
Landscape horticulture is about producing, marketing, and maintaining landscape plants. It is thus the branch of horticulture that will be of greatest interest to landscape designers and to homeowners interested in starting a new garden and committed to adorning their landscaping with the ornamental treesshrubsperennials, and annual flowers sold at nurseries and garden centers.
Along the same lines, producers and marketers of vegetables and of fruits may have studied olericulture and pomology, respectively. Olericulture is about the cultivation of vegetables, while pomology deals with fruit production. This brings us to the technical difference between fruits and vegetables:
Arguments over this distinction often spawn when people discuss the classification of the tomato. Many people are surprised to learn that it is a fruit, technically, even though it does not have a sweet taste. Why does it merit this classification? If the object in question developed from a flower on a plant and contains seeds, then it is a fruit. Likewise, pumpkins, hard-shell gourds, and ornamental gourds are all fruits (some edible, some inedible). So when you carve a pumpkin for Halloween, you are carving a fruit.
True “vegetables” are the other plant parts that you will find in the produce section of the supermarket: for example, carrots (which are roots), asparagus (which is a stem), lettuce (which is a leaf), and broccoli (we eat the flower buds of broccoli).
Finally, it is the post-harvest physiologists that grocery stores hire to prevent produce from spoiling prematurely. They, too are horticulturists.

Careers in Horticulture

In fact, the number of career paths open to you after you have received a degree in horticulture are too numerous to list in full. But here is a sampling:
  • Working with the public at an arboretum or botanical garden
  • Teaching the subject (courses at a college or outreach at a county extension office)
  • Running a business in which plants or produce are sold
  • Designing arrangements at a florist shop
  • Keeping the grass green and lushat a golf course
  • Working as a lawn care technician
  • Maintaining the landscape for a park
  • Working as a plant developer
  • Conducting research into plants for a college, for the government, or for a business
What type of career in horticulture that you choose will depend on a variety of factors. For example, if you see yourself as more of a studious sort than as a people person, it would make more sense for you to pursue work in research or in plant development than as a tour guide for a botanical garden. Some careers in horticulture (for example, teaching the subject at a university) will demand that you earn a graduate degree.

Ancient Romans Who Wrote About Horticulture

Scholars have been writing about horticulture for centuries, including ancient Greek and Roman scholars. Among the Romans, Cato the Elder, Varro, Columella, Virgil, and Pliny the Elder stand out. Virgil, better known for his Aeneid, set down his reflections on horticulture in the Georgics. As a poet, his work on the subject is appreciated more for the way he related the information than for the factual content.


Mark Williams

“Horticulture has been useful to me in that I learned what it means to care for things (plants) overtime. I learned a lot about gardening and plants in general.”

Carol Clarkson

“In the group horticulture at Cottages on Mountain Creek I go to the group and learn about horticulture.  I get to hear the technical horticulture language.  I get to see the plants.  And most importantly I get to practice horticulture. This is my horticulture testimony.”

Amanda Burns

“I like it. It seems to be a positive way to occupy time.  I wish we go out in the garden more behind the 24/7 house despite seasonal changes.”
