Tabebuia roseo-alba
Tabebuia roseo-alba, known as white ipê, ipê-branco or lapacho blanco, is a tree native to Cerrado and Pantanal vegetation in Brazil, but also appears in Argentina and more rarely in Paraguay.
This plant is frequently used as an ornamental plant and honey plant in Brazil and Argentina. On the other hand, its flowers seem to be less popular with many hummingbirds than those of other Tabebuia, being visited mostly by the occasional generalist species like the gilded sapphire.
