areas with dry to moderate rainfall. They can survive in locations with prominent dry seasons, where they can flower on the bare branches, or in more humid conditions, where they can remain evergreen. It can also be found in rocky forests, mountain slopes, and even occasionally on plains or savannas. It occupies elevations of 500 to 1000 meters but can be found up to elevations of 1500 meters. Cultivation The species is cultivated around the world in subtropical and tropical climates. In Australia, it is widely seen in cultivation in Sydney and Perth and warmer frost free climates northwards. In the mainland United States, it tolerates USDA Hardiness zones 10B to 11 (southern coastal California and the southern tip of Florida). It is also grown in Hawaii to an altitude of 2000 m. They tolerate a wide variety of soils, from acid to alkaline and sandy to clay. These plants grow best in dry to medium moisture, well-drained soils in full sun and will bloom through most of the year in tropical areas. They do not grow well in wet soils and in areas with temperatures below during the winter seasons, the plants will stop blooming and shed their leaves. Established plants are also very salt tolerant and tolerate even salt-laden winds. Widely available in nurseries, frangipanis are readily propagated by cuttings of branches taken in cooler months and left to dry for a week or more. As well as gardens and street- and park planting, frangipanis are planted in temples and cemeteries. Plumeria rubra is an important crop in Hawaii, with over 14 million flowers sold to be used in leis there in 2005. In temperate areas P. rubra must be grown under glass, in a large conservatory or similar, due to its requirement for warm conditions. However it may be placed outside in a sheltered sunny spot during the summer months. In the United Kingdom it has gained the Royal Horticultural Society’s Award of Garden Merit. Some forms in cultivation are hybrids between this species and Plumeria obtusa; these have rounded rather than pointed leaves and are less likely to be deciduous. The white and yellow cultivar "Singapore" flowers all year round in Hawaii. Coleosporium plumeriae, known as plumeria rust or frangipani rust, is a fungus which attacks young leaves of P. rubra. It causes a brownish or orange powdery coating or blistering of leaves. It has been
