Proper labeling contributes significantly to the preservation of rare Plumeria cultivars. By accurately identifying and documenting these unique varieties, growers can ensure their distinction from other cultivars. This distinction is vital for recognizing and safeguarding rare and endangered Plumeria species and hybrids. Through proper names and labeling, rare cultivars gain recognition within the Plumeria community, raising awareness about their conservation needs. Preservation efforts become more effective when enthusiasts understand the rarity and significance of specific cultivars, inspiring them to participate in conservation initiatives, propagation, and responsible cultivation practices that help sustain rare Plumeria for future generations.
