Handroanthus chrysotrichus

Mattos Handroanthus pedicellatus (Bureau & K. Schum.

Handroanthus chrysotrichus, synonym Tabebuia chrysotricha, 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 Brazil.

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.

The USDA rates it for hardiness zones 9b 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] A 2007 DNA study of various members classified in the genus Tabebuia showed that the taxon was polyphyletic, and two genera were resurrected to separate these members into three separate clades: Roseodendron, Handroanthus, and Tabebuia.

[4] Tabebuia chrysotricha was moved to Handroanthus chrysotrichus, characterized by the hardness of its wood and high lapachol content.
