Plumeria rubra L.

Plumeria rubra is a deciduous plant species belonging to the genus Plumeria.^[2] Its common names are Red Frangipani, Common Frangipani, Temple Tree, or simply Plumeria. Originally native to Mexico, Central America, Colombia and Venezuela, it has been widely cultivated in subtropical and tropical climates worldwide and is a popular garden and park plant, as well as being used in temples and cemeteries. It grows as a spreading tree to 7-8 m (20-25 ft) high and wide, and is flushed with fragrant flowers of shades of pink, white and yellow over the summer and autumn.

Taxonomy

Plumeria rubra was one of the many species first described by the father of taxonomy Carl Linnaeus, and appeared in the 1753 edition of Species Plantarum. Its specific epithet is derived from the Latin ruber "red". The epithets acuminata, acutifolia, and lutea are seen, but these are invalid. The common name in Australia is frangipani, although plumeria is used in the United States. The term melia is a Hawaiian one.^[3] The common name "Frangipani" comes from an Italian noble family, a sixteenth-century marquess of which invented a plumeria-scented perfume. It is grown extensively in southern and western parts of India, where it is named Champa or a derivative thereof such as Chaaphaa, Champige etc.

This Pink Frangipani tree,was photographed at Warje, India.

Description

Plumeria rubra grows as a spreading shrub or small tree to a height of 7-8 m (20-25 ft) and similar width. It has a thick succulent trunk and sausage-like blunt branches covered with a thin grey bark. The branches are somewhat brittle and when broken, ooze a white latex, or sap, which can be irritating to the skin and mucous membranes. The large green leaves can reach 30 to 50 cm (12-20 in) long and are arranged alternately and clustered at the end of the branches. They are deciduous, falling in the cooler months of the year. The flowers are terminal, appearing at the ends of branches over the summer. Often profuse and very prominent, they are strongly fragrant, and have five petals. The colours range from the common pink to white with shades of yellow in the centre of the flower.^[2][4] Initially tubular before opening out, the flowers are 5-7.5 cm (2-3 in) in diameter, and only rarely go on to produce seed - 20-60 winged seeds are contained in a 17.5 cm (7 in) pod.^[3]

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.^[3] The white and yellow cultivar "Singapore" flowers all year round in Hawaii.^[5]

Distribution and habitat

Its native range extends from central Mexico south through Central America to Colombia and Venezuela in South America. And in some parts of India^[1]

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.^[6] In the mainland United States, it tolerates USDA Hardiness zones 10B to 11 (southern coastal California and the southern tip of Florida).^[4] It is also grown in Hawaii to an alittide of 2000 m.^[3] They tolerate a wide variety of soils, from acid to alkaline and sandy to clay.^[4] 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.^[6] As well as gardens and street- and park planting, frangipanis are planted in temples and cemeteries.^[3]

Plumeria rubra is an important crop in Hawaii, with over 14 million flowers were sold to be used in leis there in 2005.^[7]

No weed potential has been recorded in the United States.^[4]

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 recorded from Hawaii and the east coast of Australia.^[3][8] It was first recognised by the French mycologist Narcisse Théophile Patouillard on Guadeloupe Island in the eastern Caribbean in 1902, and had reached Taiwan by 2005.^[9]
