Lesser Bougainvillea (Bougainvillea glabra) - Blooming
Bougainvilleas will reach their peaks in blooming in mid-summer. Areas that have the mildest winters will have Bougainvilleas flowering from spring through fall.Bougainvilleas can be induced to flower by not watering them for a short period of time so that the soil dries out. Do this in late spring or early summer. The idea is not to let them die from underwatering, but to provide a slight drought stress.A Bougainvillea that has deep green leaves and lacks flowers may have too much nitrogen in the soil. Flower production can be promoted by leaching out some of the nitrogen and then replacing the nutrients with a fertilizer that has relatively more potassium and phosphorus.

Bougainvilleas are native to tropical and subtropical South America, but can be grown in most places with minimal threats of frost. The showy petal-like structures that a generally mistaken to be flowers are actually modified leaves called bracts that subtend the true flowers. Although these plants are considered climbers, their climbing is limited because they do not have twining stems or tendrils. Their thorny stems are used to "bramble" over other plants or hillsides. The genus name is derived from the French Navy admiral, Louis Antoine de Bougainville, who encountered the plant in Brazil in 1768.
