Bougainvillea glabra Chois.
Bougainvillea Genus of 14 species of evergreen shrubs and trees, and evergreen and partly deciduous, sometimes thorny climbers, from forest and thickets in tropical and subtropical South America. Large woody vine, native to Brazil, flowers are grouped in cymes of 3, and each flower has a brightly colored subtending bract. Bougainvillea can become a large plant if not controlled. Many types have dangerous, stout spines. Use tall-growing vines on fences, trellises, and as sprawling ground covers. The plant prefers full sun and a well-drained potting mix. Actively growing bougainvilleas like a moist soil but should be kept drier in winter. Leaf drop occurs if the plant gets too dry but leaf drop in autumn is normal. Fertilizer recommendations vary, but any house plant fertilizer, used according to label directions, should give good results. Ideal temperatures are 70 to 80 degrees during the day and 60 to 65 degrees at night. Bougainvillea needs 14 hour nights to flower. Cut the plant back to about 12 inches after flowering. New growth can be pinched to encourage branching. Bougainvillea
