Bougainvillea spectabilis grows as a woody vine or shrub, reaching 15 to 40 feet (4.6 to 12.2 m) with heart-shaped leaves and thorny, pubescent stems. The flowers are generally small, white, and inconspicuous, highlighted by several brightly colored modified leaves called bracts. The bracts can vary in color, ranging from white, red, mauve, purple-red, or orange. Its fruit is a small, inconspicuous, dry, elongated achene.
Water a newly planted bougainvillea frequently to keep the soil moist. Once the plant is established, it blooms best if the soil is a little on the dry side. Water the plant until liquid drips through the drainage hole, then don't water again until the potting mixture feels slightly dry
