Bougainvillea grows best in dry soil, in very bright full sun, and with frequent fertilization. It requires little water once established, and in fact will not flourish if over-watered.
Bougainvillea is relatively low maintenance, and can withstand periods of neglect. However, it does benefit from regular pruning to maintain shape and encourage blooming.
Bougainvillea is a popular choice for adding vertical interest and creating focal points in gardens. It can also be kept as an indoor houseplant in temperate regions.
