Bougainvillea is a hardy, fast-growing ornamental flowering climber or shrub, famous for its bright, colorful papery bracts in shades of pink, purple, red, orange, yellow, and white. The true flowers are small and white, surrounded by showy bracts. It is widely used for compound walls, fencing, arches, pergolas, and bonsai. Bougainvillea thrives in full sunlight, requires well-drained soil, and minimal watering once established. It is drought-tolerant, low-maintenance, and ideal for tropical and subtropical landscaping.
