Tabebuia roseo alba
From Wikipedia, the free encyclopedia:
Tabebuia tree, known as Ipê-branco ou amarelo (white, purple pink or yellow ipê or Pau D'arco) in Brazil
About 100 species; see text
Tabebuia is a Neotropical genus of about 100 species of large shrubs and trees in the tribe Tecomeae of the family Bignoniaceae. The species range from northern Mexico and the Antilles south to northern Argentina. Most species are on the islands of Hispaniola (Dominican Republic and Haiti) and Cuba.
Species in this genus are important as timber trees and as ornamentals because of their showy flowers. Many species are dry-season deciduous and flower on leafless stems at the end of the dry season, making the floral display more conspicuous. The bark of several species is used medicinally. The wood is used for furniture, decking, and other outdoor uses. Remarkably, it has a fire rating of A1 (the best possible, the same as concrete), and is denser than water (it sinks). It is increasingly popular as a decking material due to its insect resistance and durability.
