PLANT DESCRIPTION
Bougainvillea is a popular ornamental, mostly valued for its multi coloured bracts. It can be used in the garden as a shrub, climber, pot plant or as a specimen plant. By keeping the view of its multiple uses there is always demand for the new coloured and forms of bracts in bougainvillea. All the present day colourful bracted bougainvilleas are developed through bud sports, mutations and inter and intra specific hybridization. There is no record of varieties evolved in bougainvillea through classical breeding in different countries. Present article will provide maximum information generated in India by different research institutes on classical and mutation breeding on bougainvillea.

BENEFITS
- It also is believed to have anticancer, antihepatotoxic, anti-inflammatory, antihyperlipidemic, antimicrobial, antioxidant, and antiulcer properties. Bougainvillea spectabilis contains pinitol, which has an insulin-like effect and has the potential for development as a treatment for diabetes.
USES
- The flowers, alone or in combination with other medicinal plants, have long been used in Mexican traditional medicine for the treatment of coughs and respiratory problems.
- A related species, B. glabra, has been found to have important properties as a botanical insecticide.
