Plumeria cultivars, which are cultivated varieties or hybrids, are named by their breeders or developers. Breeders often choose names for cultivars that highlight their unique characteristics, parentage, or personal significance. For example, a breeder may name a new Plumeria cultivar “Starlight Princess” if it has white flowers with a star-like pattern. To ensure clarity and avoid duplication, the names of Plumeria cultivars are often registered with relevant horticultural or botanical organizations. Cultivar names are essential for cataloging and identifying specific Plumeria hybrids and facilitating communication within the horticultural community.
