Frangipani (Plumeria) flowers appear in clusters at the end of the branches, and are distinctively scented and their perfume is particularly strong at night which encourages the ‘Sphinx Moth’ to visit and to collect the nectar and at the same time these moths pollinate the flowers. Unlike some flowering trees which bloom for a few days or weeks, Frangipanis goes on flowering for months on end. A few interesting facts, 1) Many Hawaiian ‘leis’ are made from frangipani (Plumeria) flowers, 2) Frangipanis are good hosts for Dendrobium orchids, 3) the frangipani is the national flower of Nicaragua and it features on some of their bank notes. In South East Asia these trees and its flowers are considered sacred. These trees/ bushes are easy to propagate all you need to do is take cuttings from the tips of a leafless limb in spring, you then to let the cuttings dry at the base before planting.
