Delonix Rexia is commonly known as Flame tree or Gulmohar and is an ornamental tree. The tree grows 10 – 18 meters tall, with a large, buttressed bole that can attain a girth of up to 2 meters. The flowers of Delonix regia are large, with four spreading scarlet or orange-red petals up to 8 cm long, and a fifth upright petal called the standard, which is slightly larger and spotted with yellow and white. Each leaf is 30 cm long with 20 to 40 pairs of primary leaflets or pinnae. Delonix Rexia demands light (requires sun) and grows weakly and sparsely under shade. The species seems to tolerate many types of soils from clay to sandy, but it prefers sandy soils. Established plants are very drought tolerant. It is used in parks, gardens and roadsides due to its bright red flowers. Even up close the individual flowers are striking: they have four spoon shaped spreading scarlet or orange-red petals about 3 in long, and one upright slightly larger petal (the standard) which is marked with yellow and white. The delicate, fern-like leaves are composed of small individual leaflets, which fold up at the onset of dusk. Gulmohar gets 30-40 ft tall, but its elegant wide-spreading umbrella-like canopy can be wider than its height. Gumohar is naturalized in India and is widely cultivated as a street tree.
