Are bougainvillea and azalea the same flower? What is the difference between the two?
Generally speaking, without professional knowledge it is quite difficult to tell bougainvillea and azalea apart, because after blooming they have similar flower shapes, and both can produce flowers in various colors such as red, pink and white, with a very striking visual effect, so they are easily confused. Below, let us distinguish them through in-depth study and observation.

In terms of morphological differences between bougainvillea and azalea, although both have "flower" bracts and their flower shapes both appear similar to a trumpet or bowl shape, on closer inspection the petals of the azalea are more obvious, because the azalea usually has five petals, the stamens extend outward, and its leaves are elliptical-ovate or obovate, with rough small hairs on both the front and back surfaces, sparsely distributed. Bougainvillea, however, usually consists of 3 small leaflets, the leaves are ovate or ovate-lanceolate, the leaf surface is hairless, while the underside is slightly pubescent, and the floral tube is light green with sparse soft hairs. In addition, flower color can also be used to distinguish them: the flowers of bougainvillea are mostly purple or magenta, while azalea flower colors are more varied, including rose, red-purple, bright red, apricot red, pink, white and so on.
As for the flowering period, bougainvillea has a longer flowering period, generally from autumn to spring, and some varieties even keep blooming until October before gradually withering. The azalea's flowering period is relatively shorter, usually in spring, generally blooming from March to May, though some varieties also bloom in summer.
Finally, in terms of growing environment, bougainvillea is native to South America and prefers a warm, humid environment with plenty of sunlight; it is a plant suitable for care in summer. If you want it to bloom abundantly, you can prune it three times a year: the first time in March-April, the second time in June-July, and the third time in August. Azaleas, however, are mainly distributed in the high mountain regions of Asia and Europe and are a typical acid-loving plant with relatively high requirements for temperature and humidity. It cannot be pruned at will; you may choose to prune it reasonably after its flowers fade. Generally, it is dormant in summer and winter, so you can only choose spring and autumn to prune it.
