What does cultivar name refer to in plant terminology?

The cultivar name in plant terminology specifically refers to the cultivated variety of a plant. This name is used to distinguish a particular variety that has been selected for specific characteristics, such as color, size, or growth habit, that are distinct from other varieties within the same species. Cultivar names are typically capitalized and may be followed by single quotes (e.g., Rosa rubiginosa 'Alberic Barbier') to indicate that the plant is a cultivated variety. This nomenclature is essential for horticulturists, gardeners, and researchers because it allows for precise identification and communication regarding particular plant varieties. Understanding cultivar names helps in the cultivation and care of plants, ensuring that specific attributes of each variety can be recognized and utilized effectively in landscaping and gardening practices.
