Bougainvillea is a vigorous, sun-loving climber famous for its dazzling masses of papery bracts in shades of magenta, pink, orange, white and red. Native to South America, it has become an iconic ornamental across India, draping walls, arches, gates and terraces in colour for much of the year. The true flowers are tiny and white, surrounded by the showy coloured bracts that give the plant its nickname 'paper flower'. Thorny and drought-hardy once established, it thrives in heat and bright sun, and can be grown as a climber, shrub, hedge or even trained as a bonsai.

Growing tips
In India keep it in the hottest, sunniest spot, water sparingly to encourage flowering, and prune after each bloom flush; too much water or shade gives leaves but few bracts.
