Description
Tabebuia aurea is a species of Tabebuia native to South America in Suriname, Brazil, eastern Bolivia, Peru, Paraguay, and northern Argentina. The common English name Caribbean trumpet tree is misleading, as it is not native to the Caribbean. It is also known as the silver trumpet tree, and tree of gold.
Although it thrives only in warmer climates, it can be also be grown in containers, especially small ones, which eventually can turn the tree into a large bonsai specimen.
Before sowing, clean the seeds. It should be sown into a well-drained, sandy compost at any time of the year, and covered thinly with sand or grit and kept moist. Keep at between 20-25 degrees celsius (68-77 degrees fahrenheit). Seeds sometimes germinate within 4 to 6 weeks although some may take very much longer so please be patient. Plant out in the open ground in warmer countries or in a large container elsewhere.
