moths into pollinating them by transferring pollen from flower to flower in their fruitless search for nectar. Insects or human pollination can help create new varieties of plumeria. Plumeria trees from cross-pollinated seeds may show characteristics of the mother tree or their flowers might just have a distinct appearance. Its fruit separate into 2 follicles with winged seeds. Propagation Plumeria blossoms are infertile. Plants of the species may be propagated by cutting stem tips in spring, allowing them to dry at their bases, then planting in well-drained soil. These are particularly susceptible to rot in moist soil. Applying rooting hormone to the clean fresh-cut end will enable callusing. Plumeria cuttings can also be propagated by grafting to an already rooted system. The Plumeria Society of America lists 368 registered cultivars of Plumeria as of 2009. In culture In Southeast Asia the plumeria tree and flower are considered sacred. A relief in the Penataran temple ruins in East Java shows a plumeria tree with its distinct flower petals and skeleton-like branches. A relief in the Borobudur temple, at the west side 1st zone, also depicts plumeria. These reliefs were created before European exploration. Borobudur was constructed in the 9th century and Penataran in the 14th century. Taken together, their dates fail to establish when plumeria came to Southeast Asia. In Mesoamerica, plumerias have carried complex symbolic significance for over two millennia, with striking examples from the Maya and Aztec periods into the present. Among the Maya, plumerias have been associated with deities representing life and fertility, and the flowers also became strongly connected with female sexuality. Nahuatl-speaking people during the height of the Aztec Empire used plumerias to signify elite status, and planted plumeria trees in the gardens of nobles. These are now common naturalized plants in South and Southeast Asia. In local folk beliefs, they provide shelter to ghosts and demons. They are also associated with temples in both Hindu, Jain, and Buddhist cultures. In several Pacific islands, such as Tahiti, Fiji, Samoa, Hawaii, New Zealand, Tonga, and the Cook Islands, Plumeria species are used for making leis. In Hawaii, the flower is called melia. In modern Polynesian culture, the flower can be worn by women to indicate their relationship status—over the right ear if seeking a relationship, and over the left if taken. Plumeria alba is the national flower of Laos, where it is known under the local name
