Bougainvillea is a genus of thorny ornamental vines, bushes, and trees belonging to the four o' clock family, Nyctaginaceae. It is native to eastern South America, found from Brazil, west to Peru, and south to southern Argentina. Different authors accept from 4 to 22 species in the genus.Bougainvillea thrives in places that are hot and relatively dry. The vines wouldn't bloom if they don't receive adequate sunshine. Bougainvillea blooms mostly during the months of November to May.Bougainvillea is a sun-lover and blooms the best when kept in a heated environment. It has huge roots and doesn't like to have them disturbed. And once they bloom, they add a colourful look to your walls, creating a pleasant vibe.Bougainvillea performs well in a relatively small container where its roots are slightly restricted. When the plant is large enough for repotting, move it to a container only one size larger. Use a regular potting soil without a high level of peat moss; too much peat retains moisture and may result in root rot. USES : Té de bugambilia, also known as bougainvillea tea in English, is an essential Mexican home remedy during cold and flu season. It's an excellent way to alleviate coughs, chest congestion and sore throats.
