Tabebuia chrysotricha (Pronunciation: tab-eh-BOO-yuh kriss-oh-TRICK-uh, /tɑːbɛˈbʊɪɑː/ /krɪsˈtrɪkʌ/), commonly known as Golden Trumpet Tree, is an evergreen tree from Brazil. It is very similar to and often confused with Tabebuia ochracea. In Portuguese it is called "Ipê amarelo" and is considered the national tree of Brazil.

Growth[edit]

T. chrisotricha grows to a height of 25 to 35 feet, with a spread of 25 to 35 feet. It has very showy golden-yellow to red flowers in the spring. These are rich in nectar and thus the tree is a useful honey plant. While it is not especially popular with hummingbirds, some of these - e.g. Glittering-bellied Emerald (Chlorostilbon lucidus) and White-throated Hummingbird (Leucochloris albicollis) - seem to prefer them over the flowers of other Tabebuia species.[1]

The Golden Trumpet Tree is grown outside Brazil as a street tree and garden tree. The USDA rates it for hardiness zones 10 through 11, and moderately drought-tolerant.

Renaming[edit]

A 2007 DNA study of various members classified under the Tabebuia family has shown that many members of the family were polyphyletic (similar characteristics not inherited from common ancestors), as such two genera have been resurrected to separate these members into three separate clades: Roseodendron, Handroanthus, and Tabebuia. [2] Tabebuia Chrysotricha has been recategorized as Handroanthus chrysotrichus, characterized by the hardness of its wood and high lapachol content. [3]
