buddliabuddleja


Buddleja, often spelled Buddleia (pronounced /ˈbʌdliː.ə/),[3] is a genus of flowering plants. It is now included in the figwort family, Scrophulariaceae, though in the past was previously classified in either the Loganiaceae or in a family of its own, the Buddlejaceae.

The roughly 100 species are mostly shrubs, a few being trees; the largest species reach 30 m (98 ft) tall, but most species rarely exceed 5 m (16 ft) tall. Both evergreen and deciduous species occur. They are native throughout the warmer parts of the New World from the southern United States south to Chile, and widely in the Old World in Africa and the warmer parts of Asia, but absent as natives from Europe and Australasia. The species are divided into two groups based on their floral type, those in the New World being dioecious, and those in the Old World being monoecious.

The botanic name has been the source of some confusion. By the usual practice of botanical Latin, the spelling of a generic name made from "Buddle" would be "Buddleia". However, Linnaeus wrote it down as "Buddleja", and never changed it, so by the rule of naming priority, "Buddleja" should be preferred, though the i/j interchange could be modernized as an orthographical variant. Even so, the usage is confused, and inconsistencies are common, even within single texts.

Some species are commonly found as escapees from the garden. B. davidii in particular is a great coloniser of dry open ground; in towns in the United Kingdom, it often self-sows on waste ground or old masonry, where it grows into a dense thicket, and it is listed as an invasive species in many areas. It is frequently seen beside railway lines, on derelict factory sites and after the Second World War on urban bomb sites.
Within the United States, it is classified as a noxious weed by the states of Oregon and Washington.
