Learn the difference between scientific and common plant names and how they impact communication and identification. Understand the advantages of scientific names for accuracy and universality, while common names provide familiarity. Find out how to balance both naming systems to enhance botanical knowledge and foster connections with plants.


Are you ever confused by the various names plants are called? One plant can have multiple common names, and different plants can share the same common name. This confusion can make it challenging to communicate and accurately identify plants. However, there is a solution: scientific names. In this article, we will delve into the glossary and terminology behind scientific and common plant names. By understanding the difference between these two types of names, you can expand your knowledge of plants, enhance communication, and avoid misidentification. So, let’s embark on this botanical journey to explore the fascinating world of plant names!

Scientific Names: A Universal Language for Botanists

Scientific names, also known as botanical names or Latin names, are an internationally recognized system used by botanists and horticulturists to identify and classify plants. Unlike common names, which can vary based on region, language, or personal preference, scientific names provide a universal and precise way to refer to plants.

The Binomial Nomenclature System

Scientific names follow a hierarchical system called binomial nomenclature, invented by Swedish botanist Carolus Linnaeus in the 18th century. According to this system, each plant is assigned a two-part name: the genus and the specific epithet.

  • Genus: The genus represents a closely related group of plants that share common characteristics. It is always capitalized and written in italics (or underlined).
  • Specific Epithet: The specific epithet narrows down the identification to a particular species within the genus. It is written in lowercase letters and is also italicized (or underlined).

For example, let’s consider the scientific name Rosa canina. In this case, Rosa represents the genus, and canina is the specific epithet. Together, they form the scientific name for the dog rose, a well-known flower species.

Advantages of Scientific Names

Scientific names offer several advantages over common names. Firstly, they provide a unique identification for each plant species. While common names can be shared by different plants or vary across regions, scientific names remain consistent and universally recognized.

Secondly, scientific names allow for precise communication and accurate identification, especially among scientists, researchers, and botanists. When discussing plants, using scientific names ensures that everyone is referring to the same species, regardless of their cultural background or native language.

Thirdly, scientific names help avoid confusion caused by variations in common names. Different regions or individuals may use different common names to refer to the same plant, leading to inaccuracies and misunderstandings. By relying on scientific names, you can bypass this confusion and ensure clarity in plant identification.

Remembering Scientific Names

Although scientific names may seem intimidating at first, they can become relatively easy to remember with practice. Many scientific names are derived from Latin or Greek words, which follow specific patterns and meanings. By understanding the roots and patterns behind scientific names, you can gain insight into a plant’s characteristics or habitat.

Common Names: Familiar and Regional Names for Plants

Unlike scientific names, common names are simple and familiar names given to plants. They are often based on appearance, characteristics, or practical uses of the plant. Common names can vary from one region to another, leading to different names for the same plant. For example, a plant may be known as “lady’s slipper” in one region but referred to as “moccasin flower” in another.

Variability of Common Names

The variability of common names is a result of linguistic, cultural, and regional differences. Common names can differ not only between countries but also within the same country. Different regions, counties, or even individual gardeners may use different names for the same plant.

Moreover, some common names can be misleading or ambiguous. For instance, a plant named “tiger lily” may not necessarily belong to the true lily family. It is essential to keep in mind that common names are not standardized and can sometimes be subjective.

Common Names in Marketing and Communication

Despite the variability and potential confusion, common names play a crucial role in marketing and communication within the gardening and horticulture industry. Plant nurseries, garden centers, and retailers often assign popular or marketable common names to plants to make them more appealing to customers.

While scientific names provide accurate identification, common names are often more accessible and easier to remember for casual gardeners and enthusiasts. They allow for informal conversations and sharing of gardening experiences without the need for botanical expertise.

Understanding and Balancing Both Names

While scientific names offer precision and accuracy, and common names provide familiarity and accessibility, it is essential to understand and balance the use of both names. Each naming system serves its purpose and can be valuable in different contexts.

Scientific names are the foundation of botanical taxonomy, research, and precise plant identification. They allow for global communication and ensure clarity among experts. However, it is crucial to keep in mind that generalizations about a plant’s characteristics or invasiveness should not be made solely based on the genus it belongs to. Different species within the same genus can have varying characteristics and impacts.

On the other hand, common names are useful for casual conversations, gardening advice, and building connections with plants on a more personal level. They reflect the cultural significance and regional context of plants. However, it is important to be aware of the potential variability and limitations of common names, especially when discussing plants with people from different regions or backgrounds.

By understanding and using both scientific and common names, you can expand your botanical knowledge, enhance communication, and avoid misunderstandings. Scientific names provide accuracy and precision, while common names offer familiarity and accessibility.


In conclusion, understanding the difference between scientific and common plant names is essential for effective communication, accurate plant identification, and expanding our botanical knowledge. Scientific names provide a universal language for botanists and ensure clarity and precision in plant identification. On the other hand, common names offer familiarity, accessibility, and regional context. Both naming systems have their advantages and serve different purposes. By balancing and using both scientific and common names, we can enhance our understanding of plants and foster meaningful connections with the natural world.
