Tabebuia chrysotricha (pronunciation: /ˌtæbᵻˈbjuːiə ˌkrɪsoʊˈtrɪkə/ tab-i-BEW-i-ə kris-o-TRIK-ə), commonly known as the golden trumpet tree, is a semi-evergreen/semi-deciduous (shedding foliage for a short period in late spring)[1] tree from Brasil. 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 Brasil.

Growth

T. chrysotricha grows to a height of 5 to 8 m (15 to 25 ft), sometimes up to 20 m (50 ft),[1] with a spread of 8 to 11 m (25 to 35 ft). 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.[2]

The golden trumpet tree is grown outside Brasil as a street tree and garden tree. The USDA rates it for hardiness zones 10 through 11, and moderately drought-tolerant.

Concern has been raised that it is becoming a weed in tropical and sub-tropical Australia, though it has not yet been declared.[3]

Renaming

A 2007 DNA study of various members classified under the Tabebuia genus has shown that many members of the taxon 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.[4] Tabebuia chrysotricha has been recategorized as Handroanthus chrysotrichus, characterized by the hardness of its wood and high lapachol content.[5]
