The tree is sometimes harvested from the wild for local use of its wood. It can be used as a pioneer when restoring native woodland and has an exuberant flowering display so can be grown as an ornamental in landscaping, as a street tree etc[
S. America - Argentina, Paraguay, southwest Brazil, Bolivia.

Mainly found in the subtropics, the tree enters the tropics in Brazil and Bolivia, where it is usually found at elevations below 600 metres, but can ascend to just over 1,000 metres.
Grows best in a sunny position[
The tree has a moderate rate of growth, reaching a height of around 2 metres within two years from seed[
The tree resprouts freely from the base after being felled[

This tree is unusual in the genus for being without any lapachol in its wood. Lapachol has acquired a high reputation for its medicinal uses[
The tree resprouts freely after being cut down, has a relatively fast rate of growth and is tolerant of full sun. It can be grown as a pioneer when restoring native woodland[
The wood is fine-textured, cross-grained, moderately heavy, with moderate mechanical properties, not very durable. It is only used locally, for purposes such as boards, linings etc[
The wood is used for fuel and to make charcoal[
Seed - it has a short viability and so is best sown as soon as it is ripe in a sunny position in a nursery seedbed. A germination rate in excess of 80% can usually be expected, with the seed sprouting within a few days[
]. When the seedlings are 4 - 6cm tall, pot them up into individual containers and they should be ready to plant out 4 - 5 months later.
