The scientific name provides a unique, universal identifier for each plant. It uses a two-part Latin designation (genus and species) that remains constant worldwide, so every plant species has one formal name recognized in science, horticulture, and conservation. Common names vary by language and region and can apply to multiple species or change over time, which can cause confusion. A brand name is a marketing label, not a scientific identifier, and a family name refers to a higher taxonomic group rather than to the individual species. Using the scientific name avoids ambiguity and ensures precise communication.
