No other bloom is comparable to that of bougainvillea. It is often profuse enough to nearly obscure the foliage. The color is remarkably vibrant. Magenta is the most popular color. Purple might be the second most popular color. Other cultivars bloom in delightfully rich hues of pink, red, orange, yellow and white. Some bloom with double flowers. A few dwarf cultivars have variegated foliage.
Bougainvillea is a thorny vine that leans on its support, rather than cling to it. Like climbing roses, it must be tied or woven into trellises. Larger cultivars can mix with the branches of trees and big shrubs to eventually reach more than thirty feet high. Many cultivars stay much lower. Some grow slowly, and do not get more than three feet tall. The lush foliage is evergreen with regular watering.
However, bougainvillea does not want too much water, and actually prefers to get a a bit dry between regular irrigation. Excessive irrigation may promote vegetative growth while inhibiting bloom. Excessive fertilizer does the same. Sunny and warm exposure promotes fuller bloom. In late spring, the first and most profuse of perhaps a few bloom phases can continue for more than a month.
