[Why We Use Botanical Names for Identifying Plants You don't have to learn Latin to grow beautiful plants. However, knowing a little bit about how and why plants are given their names, can be valuable knowledge when you are looking for growing advice or when you are shopping for a plant.
Plants are given botanical names based on an international system for naming each individual plant... Plants are given a first name called the "genus," and a second name called the "species". Additional words may be added to the name to describe further subdivisions. This system provides people from throughout the world a universally accepted name for each single plant. The words used are a mixture of Latin, Greek, and native names.]
If only human beings consent to signify themselves always by a "universally accepted name" consisting of two or three parts! [TNM]
