Proper labeling improves the accuracy of Plumeria cultivar databases by ensuring that each cultivar’s entry is supported by its proper name. When enthusiasts, organizations, or researchers create cultivar databases, they rely on proper names as unique identifiers for each entry. With accurate labeling, the database maintains integrity, providing reliable information for users seeking details about specific cultivars. As the number of registered cultivars increases, proper labeling becomes essential for organizing and referencing the growing collection of Plumeria varieties. By enhancing the accuracy and integrity of Plumeria cultivar databases, proper labeling contributes to the accessibility of cultivar information, benefiting the entire Plumeria community and facilitating further research and conservation efforts.
