The rows of purple flowers on Kedu Avenue in Meizhou, Guangdong are so beautiful. I wonder what their names are.

Hello, listen to your description, it should be bougainvillea, which is widely planted in southern China, and can only be raised in greenhouses in the north. Named for its triangular bracts.

Bougainvillea has leaves on its bracts, so it is also called bougainvillea. But in fact, bracts are neither flowers nor leaves. Its flowers grow in bracts and are very small. Although its stems and leaves are Du, its leaves and flowers can be used as medicine.

First, the morphological characteristics of bougainvillea

The flowering time of bougainvillea is related to the region. Most of the southern areas bloom in winter and spring, and most of the northern greenhouses bloom in March-July. Its bracts are like petals, the color is purple or magenta, and the three bracts are distributed in a triangle. But real flowers grow in bracts, and flowers are too small to be easily seen.

The bracts of bougainvillea are leaflike, so it is also called bougainvillea.

Second, growing habits

Bougainvillea is native to Brazil and is suitable for growing in a warm and humid climate. If the air is too dry, it will hibernate. In daily maintenance, we should provide enough light and water properly at the same time, so as not to let the basin accumulate water.

Third, the planting technology of bougainvillea

1, soil

The cultivation substrate of bougainvillea should be loose, breathable, well drained, rich in organic matter and weakly acidic. You can choose loam or sandy loam and mix one tenth of organic fertilizer. If it is clay, appropriate amount of perlite and river sand can be added to increase air permeability.

2. Management technology

Bougainvillea can be transplanted in the growing season. Before transplanting, about one third of the substrate should be added to the pot, and then the branches and roots of the seedlings should be properly trimmed and put into the pot, and the substrate should be filled 3 cm away from the pot surface to make it firm and permeable.

Bougainvillea is a sunny plant, which can be shaded properly when transplanted, but it is not suitable to shade again after the seedlings are restored to avoid excessive internodes and inflorescences lodging. Organic water fertilizer and potassium dihydrogen phosphate with concentration less than 0.3% should be applied 2-3 months before flowering, and water-soluble fertilizer of Haihewei can be selected.
