A botanical name is a scientific name that is used to identify a plant species. It is typically composed of two parts: the genus and the species. For example, the botanical name for the common sunflower is Helianthus annuus, where "Helianthus" is the genus and "annuus" is the species. Botanical names are standardized and internationally recognized, making them useful for researchers, horticulturists, and other professionals who work with plants.
