Tabebuia rosea

Tabebuia rosea, also called pink poui, and rosy trumpet tree is a neotropical tree that grows up to 30 m and can reach a diameter at breast height of up to 100 cm. The Spanish name roble de sabana, meaning "savannah oak", is widely used in Costa Rica, probably because it often remains in heavily deforested areas and because of the resemblance of its wood to that of oak trees. It is the national tree of El Salvador, where it is called "Maquilíshuat".
