About

Handroanthus heptaphyllus, commonly referred to as the pink trumpet tree or pink tab, is a Bignoniaceae tree native to tropical and subtropical regions of South America. It grows in the high forest watershed of the Paraná River, Paraguay River and Uruguay River. It has a limited distribution, almost exclusively inhabiting low lands with wet and deep soils, where it forms part of the upper layer of tree cover.

Along with all the other species in the Handroanthus genus, it is the national tree of Paraguay, as proposed by the School of Chemical Sciences at the National University of Asunción in celebration of the bicentenary of Paraguay's independence.
