Dear gardener,

The "flowers" of bougainvillea are actually adapted leaves called bracts. The colours produced for sale are generally a result of cross-breeding. New buds can also produce natural hybrid sports. The genetics is complex, and the plants are quite variable.

The colour of the leaves can be a natural occurrence, or caused by an introduced virus. Plants with variegated leaves can sometimes lose this trait over time.

Flowering is dependent on day length and light intensity, similar to poinsettias. The colour of the bracts may be affected by temperature, nutrition, soil acidity and moisture. Bougainvillea plants thrive in slightly acidic soils (5.5 to 6.0). Unfortunately, it is not possible for you to control the colour. But growing a healthy plant should provide you with lovely blooms none the less.
