Bougainvillea
General Description
The genus Bougainvillea comprises about 18 species. They are woody, scrambling, thorny vines, shrubs and small trees native to South America. The genus is named for Louis Antoine de Bougainville, a French explorer who sailed around the world in 1767 and discovered the plant in the area of Brazil. There are several commercially important species and hundreds of cultivated varieties.
Generally, these plants are evergreen but some may be semi-evergreen for a short time during winter. The leaves are simple, heart or oval-shaped with pointed tips. The branches are usually woody and often grow long and twine.
Bougainvilleas are grown for their garishly bright blooms. The true flowers are small, tubular and inconspicuous but are surrounded by large, bright, papery petal-like leaves called bracts. Large clusters of the blooms appear at the ends of the branches in abundance during the late winter and early spring. A few are produced all year round when conditions are right. The bracts come in practically all colors of the rainbow. The fruit, when present, is long and resembles a green bean.
Culture and hardiness is species dependent, but most bougainvilleas prefer sunny, warm conditions and require very well-drained soil. They tend to be drought tolerant, but look best with occasional applications of water. Be careful with water, fertilizer and pruning because too much of any of these will reduce or completely curb flowering.
Hot, tropical color and a tough habit make Bougainvillea popular plants for landscapes in frost-free climates. Plant form dictates use. Some are large rambling lianas while others are very compact. Bougainvillea may be planted as free-standing specimens, hedges, trailing vines or groundcover plants. They are also popular as container or greenhouse specimens where not hardy.
