Delonix regia is a medium-sized deciduous tree that grows to about 10 m (33 ft). The bark is light brown. Often creased at branches, it has prominent lenticels. [3] The flowers are large, with four spreading scarlet or orange-red petals up to 8 cm (3 in) long, and a fifth upright petal called the standard, which is slightly larger and spotted with yellow and white. They appear in corymbs along and at the ends of branches. The naturally occurring variety flavida (Bengali: Radhachura) has yellow flowers. [4] The pods are green and flaccid when young, then turn dark-brown and woody as they mature. They can be up to 60 cm (24 in) long and 5 cm (2 in) wide. The seeds are small, weighing around 0.4 grams (6.2 grains) on average. The compound (doubly pinnate) leaves have a feathery appearance and are a characteristic light, bright green. Each leaf is 30–50 cm (12–20 in) long with 20 to 40 pairs of primary leaflets or pinnae, each divided into 10–20 pairs of secondary leaflets or pinnules. Pollen grains are elongated, approximately 52 μm in size.[ citation needed ]

In India, the trees are bare during the winter months from December to February. New leaves start to form in March-April. Flowers start to appear in April, reaching full bloom in May. Fruit pods are present for many months. [3]

Distribution

Delonix regia is endemic to Madagascar's dry deciduous forests, but has been introduced into tropical and sub-tropical regions worldwide. In the wild it is endangered, but it is widely cultivated elsewhere and is regarded as naturalised in many of the locations where it is grown. [3]

North America

In the continental United States, it grows in South Florida, Central Florida, [5] and in the Rio Grande Valley of South Texas. Hawaii is another location where the species is grown. It also grows in humid parts of Mexico, especially in the southwest states like Campeche, Chiapas, Oaxaca, Tabasco, Veracruz, and Yucatan.

Caribbean and Central America

In the Caribbean it is featured in many Dominican and Puerto Rican paintings. It can also be found in Belize, The Bahamas, Costa Rica, Cuba, Haiti, Honduras, Nicaragua, the U.S. Virgin Islands, Sint Maarten, Trinidad and Tobago, the Cayman Islands, Grenada,[ citation needed ] Jamaica, Curaçao, Dominica, Saint_Vincent_and_the_Grenadines and Saint Lucia. It is the national flower of St. Kitts and Nevis. It can also be found in Bermuda. The town of Peñuelas, Puerto Rico, located about 12 miles or 19 kilometers west of Ponce, is nicknamed El Valle de los Flamboyanes ("The Valley of the Poinciana Trees"), as many flamboyant trees are found along the surrounding Río Guayanes, Río Macana, and Río Tallaboa rivers.

South America

It grows in Paraguay and Brazil. [1]

The tree is planted in India, where it is referred to as the May-flower tree, Gulmohar or Gul Mohr. [6] In West Bengal, and Odisha it is called Krishna Chura (কৃষ্ণচূড়া/କୃଷ୍ଣଚୂଡ଼ା). In Sri Lanka it is known in Sinhala as the Maara tree, although for a short while it was known as the Lamaasuriya tree after Le Mesurier, the British civil servant who was responsible for introducing it as a shade tree. [7] It is also grown in Karachi, Pakistan. In Mauritius and La Réunion it announces the coming of the new year.

In Bangladesh it is known as krisnachura(কৃষ্ণচূড়া). You can find this tree in various places in Bangladesh. It is found all over Dhaka City and is one of the iconic symbols of the Bengali month of Boishakh. In Nepal it is known as Shirish.

Southeast Asia

In Myanmar, where it is called Sein-pann-ni, the time of flowering is March in the south and early to late April in the north. It is planted in gardens and as a roadside tree. In Myanmar, this tree is a sign of the Thingyan Festival (13–16/17 April). In the Philippines, its flowering signals the imminent arrival of the monsoon rains. It also grows in Thailand and Indonesia. In Vietnam it is called "phoenix flower" and mostly grows in Haiphong. In Malaysia, it is called "Semarak", which used to be the name of a street in the country's capital city, Kuala Lumpur, now renamed as Jalan Sultan Yahya Petra where one of the oldest and highest ranked Malaysian universities, the University of Technology Malaysia's Kuala Lumpur campus is located. "Semarak Api" is also the official flower of the Sepang district.

East Asia

It grows in Southern China such as in Hong Kong. It is the official tree in Tainan, Taiwan; Xiamen, Fujian Province, and Shantou, Guangdong Province, People's Republic of China. National Cheng Kung University, a university located in Tainan, included royal poinciana on its emblem.

Australia

It is very widely grown in Northern Australia, in the southern extremes previously limited to South East Queensland where it is a popular street tree in the suburbs of Brisbane. [8] It blooms successfully in Sydney and other parts of New South Wales. [9]

Micronesia

It grows in Guam, and is the official tree of the Commonwealth of the Northern Mariana Islands.

Africa

The species is present in several Southern African countries, such as South Africa, Zimbabwe, Malawi, Zambia and Namibia. [1]

Cultivation

Required conditions

The royal poinciana requires a tropical or near-tropical climate, but can tolerate drought and salty conditions. It thrives in open, free-draining sandy or loamy soil enriched with organic matter. The tree does poorly in heavy or clay soils, and flowers more profusely when kept slightly dry.

Propagation

Seeds

The royal poinciana is most commonly propagated by seeds. Seeds are collected, soaked in warm water for at least 24 hours, and planted in warm, moist soil in a semi-shaded, sheltered position. In lieu of soaking, the seeds can also be "nicked" or "pinched" (with a small pair of scissors or nail clipper) and planted immediately. These two methods allow moisture to penetrate the tough outer casing, stimulating germination. The seedlings grow rapidly and can reach 30 cm (12 in) in a few weeks under ideal conditions.

Cuttings

Less common, but just as effective, is propagation by semi-hardwood cuttings. Branches consisting of the current or last season's growth can be cut into 30 cm (12 in) sections and planted in a moist potting mixture. This method is slower than seed propagation (cuttings take a few months to root) but is the preferred method for ensuring new trees are true to form. As such, cuttings are a particularly common method of propagation for the rarer yellow-flowering variety of the tree.

Uses

In addition to its ornamental value, it is a useful shade tree in tropical conditions, because it usually grows to a modest height (mostly 5 m or 15 ft, but it can reach a maximum height of 12 m or 40 ft) but spreads widely, and its dense foliage provides full shade. In areas with a marked dry season, it sheds its leaves during the drought, but in other areas it is virtually evergreen.

Cultural significance

In the Indian state of Kerala, royal poinciana is called kaalvarippoo (കാൽവരിപ്പൂവ്, kālvarippūv) which means "the flower of Calvary". There is a popular belief among Saint Thomas Christians of Kerala that when Jesus was crucified, there was a small royal poinciana tree nearby his Cross. It is believed that the blood of Jesus Christ was shed over the flowers of the tree and this is how the flowers of royal poinciana got a sharp red color. [10] It is also known as Vaaga in many areas of Kerala.

Its blossom is the national flower of St. Kitts and Nevis, [11] and in May 2018 the royal poinciana was adopted by the city of Key West as its official tree. [12] Known locally as semarak api, Delonix regia is the city flower of Sepang, Selangor, Malaysia. [13]

In Vietnam, this tree is called Phượng vỹ, or "phoenix's tail", and is a popular urban tree in much of Vietnam. Its flowering season is May–July, which coincides with the end of the school year in Vietnam. Because of this timing, the flower of poinciana is sometimes called the "pupil's flower". The tree is also commonly found on school grounds in Vietnam, however after several incidents where a tree has fallen onto students, with one student killed, schools started cutting down or severely pruning the trees. [14] Hải Phòng is nicknamed Thành phố hoa phượng đỏ ("City of red poinciana").

The song "Poinciana" was inspired by the presence of this tree in Cuba. [15] [16]
