spectabilis, commonly referred to as Great Bougainvillea, stands out for
its striking beauty and ecological significance. This article provides an
overview of Great Bougainvillea, its sources, benefits for humans and the

Overview of Great Bougainvillea
Great Bougainvillea (Bougainvillea spectabilis) is a
woody, perennial vine or shrub that belongs to the Nyctaginaceae family. It is
characterized by its thorny branches, elliptical leaves, and brightly colored
bracts that surround small, inconspicuous flowers. The bracts, often mistaken
for petals, come in a variety of colors, including pink, purple, red, orange,
and white, making the plant a popular choice for ornamental purposes.
The plant is named after the French explorer Louis Antoine
de Bougainville, who first encountered it in Brazil during the 18th century.
Since then, Great Bougainvillea has been widely cultivated and naturalized in
tropical and subtropical regions around the world.
Sources of Great Bougainvillea
Great Bougainvillea is native to the coastal areas of
Brazil, where it thrives in warm, sunny climates. It has since been introduced
to various parts of the world, including Asia, Africa, Australia, and the
Mediterranean region. The plant is commonly propagated through cuttings, which
root easily in well-drained soil and require minimal maintenance once
established.
