About Handroanthus uleanus
Handroanthus uleanus, commonly known as Ipê Amarelo, is a stunning tropical tree from the Bignoniaceae family, renowned for its spectacular vibrant yellow bloom. Its trumpet-shaped flowers completely cover the canopy in spring, creating an unparalleled visual spectacle. It is ideal as an ornamental tree in large gardens, parks, or as a specimen plant to provide an intense focal point of color.
Native range
South America, especially in Brazil, Paraguay, and northeastern Argentina.
Care tips
It requires full sun exposure for abundant flowering and optimal growth, at least 6 hours daily. Watering should be regular during dry periods, especially in its first years, avoiding waterlogging; once established, it is quite drought-tolerant. It prefers well-drained, fertile, and slightly acidic soils. A common mistake is planting it in areas with a risk of severe frosts, as it does not tolerate them.
