Bougainvillea spectabilis
Medium · Some experienceAbout Beautiful Bougainvillea
Bougainvillea spectabilis is a vigorous, thorny, tropical climbing shrub famous for its overwhelming displays of vibrant color — the 'flowers' are actually papery bracts surrounding tiny white true flowers. Colors include magenta, purple, red, orange, pink, white, and multicolors. Native to Brazil, it thrives in hot, dry conditions and poor soil, blooming most profusely when slightly stressed. Vines can cover entire buildings in tropical regions. It requires full sun and warm temperatures; frost kills it. In containers, restricting root space encourages heavier blooming.

History
Bougainvillea spectabilis is native to the coastal forests of Brazil, Peru, and Argentina. It was collected during Louis-Antoine de Bougainville's 1766-1769 French circumnavigation by the expedition's naturalist Philibert Commerson, and named by him for his captain. Historical evidence strongly suggests the actual field discovery was made by Jeanne Baret, Commerson's housekeeper and common-law partner, who had signed aboard disguised as his male valet to evade the French Navy's ban on women — making her the first woman to sail around the world.
The plant spread through 19th-century European greenhouse culture and became iconic in Mediterranean North Africa, southern Europe, and later in California, Florida, Arizona, and throughout the tropics. The colorful "flowers" are actually papery bracts surrounding inconspicuous true flowers.
Bougainvillea was discovered in 1768 during Louis Antoine de Bougainville's circumnavigation of the globe — the expedition's botanist, Philibert Commerçon, collected specimens in Rio de Janeiro (though his assistant, Jeanne Baret, disguised as a man, likely did the actual collecting — making her the first woman to circumnavigate the world). In the Mediterranean, bougainvillea cascading over white walls became the defining image of Greece, Spain, and southern Italy. The city of Shenzhen, China has planted millions, making bougainvillea its official flower.
