Bongi villa is a playful term many home gardeners use to refer to the bougainvillea plant, a showy, evergreen vine. Desirable for its colorful bracts and hardy nature, this versatile plant can be trained to grow as a shrub, tree or ground cover, or planted in containers and left to trail over the sides, according to the University of Florida. Bougainvilleas grow year-round in United States Department of Agriculture (USDA) hardiness zones 9B through 11, or as annuals or in containers in cooler climates.
Plant or place your bongi villa in a location where it will receive full sun, which is defined as a minimum of six hours of sunlight per day. This tropical plant will bloom profusely if it receives enough sunlight.
Water regularly. While the bougainvillea is tolerant of drought conditions, the plant flowers much more profusely if the soil is kept cool and slightly moist but not constantly wet, according to the University of Hawaii.
Prune often to maintain the shape of the vine or to train it to grow on one or multiple trunks. The best time to prune is just after flowering occurs and the bracts are starting to fade. The plant can tolerate vigorous pruning, suggests the University of Florida, but take care to avoid the long thorns.
Fertilize bougainvillea with a balanced food (10-10-10) at least once a month during the growing season (late winter to late summer). Follow the directions on the label for the size and age of your plant.
