Handroanthus
Showy-flowered trees from Central and South America, valued for timber and ornament
Handroanthus is a group of about 30 tree species in the Bignoniaceae family, native to parts of Central and South America. These trees are grown for their striking yellow or magenta flowers and very hard wood, used in landscaping, timber, and traditional remedies.
- Handroanthus trees produce large, showy yellow or magenta flowers.
- Their wood is among the hardest and most durable in the Americas.
- Several species are national emblems in South American countries.
- The bark is used for herbal teas in South America.
- Handroanthus is widely planted as an ornamental tree in warm climates.
What does Handroanthus look like?
Handroanthus trees can reach considerable heights and sometimes appear as shrubs. Their leaves are divided into several leaflets, often five to nine, and have a covering of scales and hairs. The flowers are large, tubular, and either bright yellow or, in a few species, magenta with a yellow throat. These blooms cluster at branch ends, often before the leaves return, making them stand out. The fruit is a long capsule that splits open to release thin, winged seeds. The wood is extremely dense and heavy, with a heartwood that is olive brown to black.
Where does Handroanthus come from?
Handroanthus grows wild from Central America through much of South America, including Brazil, Paraguay, Argentina, Chile, and parts of the Caribbean. The genus was first described in 1970, named after Brazilian botanist Oswaldo Handro. For a time, its species were grouped with Tabebuia, but DNA studies in 2007 led to Handroanthus being recognized as a separate group again. These trees have become popular ornamentals and have naturalized in many warm regions beyond their original range.
When and how Handroanthus blooms
Handroanthus trees flower at the end of the dry season, often when their branches are bare of leaves. They are grown from seeds, which are easily spread by wind due to their wings. The trees thrive in tropical and subtropical climates and are planted in gardens, parks, and along streets for their vivid floral displays. Their wood is harvested for timber, especially for outdoor uses.
How Handroanthus is used
People plant Handroanthus for their showy flowers in landscaping and public spaces. Several species provide timber that is highly valued for its durability and resistance to insects, used in decking, furniture, and carving. The bark is sold in South American markets and brewed as a tea called pau d'arco or lapacho, though its medicinal effects are unproven. Indigenous peoples have used the wood for making bows.
Kinds of Handroanthus
The genus includes about 30 species, such as Handroanthus impetiginosus (pink ipê), H. chrysotrichus, H. ochraceus, H. chrysanthus, H. guayacan, H. serratifolius, and H. billbergii. Some species are especially known for their timber, while others are favored for their ornamental flowers. The color of the flowers varies by species, with most being yellow and a few magenta.
What Handroanthus means
Handroanthus species are official emblems in several countries: Brazil (H. serratifolius), Ecuador (H. chrysanthus), Paraguay (H. heptaphyllus), and Venezuela (H. billbergii). The trees are widely recognized for their beauty and are a common sight in tropical cities. Their wood is highly prized, and the trees have cultural importance in both traditional crafts and national symbolism.
