Lesser Bougainvillea
Bougainvillea glabra
Medium · Some experienceAbout Lesser Bougainvillea
Bougainvillea glabra, the lesser bougainvillea, is more compact and less thorny than B. spectabilis, making it better suited for containers and smaller gardens. It produces profuse papery bracts in magenta, purple, white, and pink. Native to Brazil, it blooms more freely than B. spectabilis, with some varieties flowering almost continuously in warm climates. The 'glabra' (smooth) name refers to its less hairy leaves. Popular cultivars include 'Sanderiana' (deep purple) and 'Snow White.' It can be trained as a standard, hedge, or bonsai. Like all bougainvillea, it demands heat, sun, and good drainage.

History
Bougainvillea glabra is native to Brazil and was introduced to European cultivation in the mid-19th century. It differs from B. spectabilis chiefly by its smoother, less hairy leaves and smaller, thornless or nearly thornless habit — making it the preferred parent of most modern garden cultivars. Twentieth-century horticultural development, particularly in India, Australia, and the United States, produced the extensive cultivar range now sold: "Barbara Karst," "Mrs. Butt," "San Diego Red," "Miss Manila," and the double-bracted "Double Pink."
It is the official municipal flower of multiple warm-climate cities: Shenzhen (China, since 1988), Naha (Japan), Tainan and Pingtung (Taiwan), Ipoh (Malaysia), and Guam (USA). Its ability to produce vivid walls of color on walls and pergolas with minimal water made it a signature of modernist tropical architecture. Bougainvillea glabra was instrumental in making bougainvillea one of the most commercially important ornamental plants in the tropics and subtropics.
Its more compact habit and free-flowering nature made it adaptable to smaller gardens and containers. In Southeast Asia, bougainvillea bonsai is a respected art form — specimens with thick, gnarled trunks cascading with purple bracts can sell for thousands of dollars. Thailand and the Philippines produce some of the world's finest bougainvillea bonsai. In Singapore, bougainvillea hedge-trimming into geometric shapes along highways is an iconic part of the city's designed landscape.
