Tabebuia roseo-alba ¨Ipê-branco”

Tabebuia roseo-alba

Hello, dear readers!

Today I'd like to introduce you to a beautiful tree that I had the opportunity to study a few years ago. Since I love to talk about plants 😊, in this post, I'll share some interesting facts about the stunning Tabebuia roseo-alba (Ridl.) Sandwith, an ornamental tree best known for its spectacular white-to-pale pink blossoms.💮💮💮

It belongs to the Tabebuia genus. Tabebuia is the largest genus of the Bignoniaceae family and comprises over 100 species from tropical and subtropical areas. 

Trumpet trees (English common name) or Tabebuia roseo-alba is a species popularly known as“ipê-branco”, “ipê-do-cerrado”, or “pau-d’arco” in Brazilian Portuguese. In fact, “Ipê-branco” is also a Brazilian common name for other species of the genera Tecoma and Bignonia.

Botanical Characteristics

Tabebuia roseo-alba is a native wild species to Brazil recognized for its exuberant white-pinkish flowering, dense bluish-green foliage, and the pyramidal shape of the crown(1,2). The species’s name comes from the color of its flowers ( roseo means rosa, rose or pink, and alba means white in Latin names).

Mature tree in Campo Grande, MS, Brazil

Flowers of T. roseo-alba

The “ipê-branco” can reach 5- 10 m tall and is a deciduous tree (the leaves fall off at maturity), which is evident when you see the lush white-pinkish flowers and a few green leaves.

The leaves are characterized by having a trifoliate leaf or leaflets as an adult, which differs from some other Tabebuia species, with 5 leaflets, similar to our hand.

Seeds 

Fruits are dehiscent bivalve capsules resembling a large pod. When mature, the built-in line opens to release the seeds.

Seeds (on right picture) are small and winged (adaptations that allow them to be carried by the wind), and a kilogram of the fruit may have approximately 71,000 seeds. That’s a lot of seeds!!

What is its biological life cycle (plant phenology?

The beautiful flowers occur from August to October (sometimes flowering repeats around September, but with less intensity), and fruiting begins in October, when the plant is completely stripped of its foliage ( the most beautiful phase of it) and produces many seeds that are dispersed by the wind.

What is the geographic area where it can be found?

Origin: South America. It occurs in Brazil and extends across the northern states to the southeastern states of Brazil(3) and parts of Paraguay, and it was introduced in Argentina for landscape purposes (4).

It occurs in primary forest and secondary formations in the Caatinga (Brazilian dry land), the Pantanal wetland of Brazil and Paraguay, the Atlantic forest, and the Brazilian Cerrado (1,2,3).

What is its habitat?

This species is a deciduous (loses its leaves), heliophilous (it needs a lot of light and open areas), and selective xerophytic plant (it likes dry environments), characteristic of rocky and limestone outcrops of semi-deciduous forests (1). This characteristic facilitates its use in the restoration of dry and stony terrain. T. roseo-alba can tolerate rapid fire and is a roadside colonizer in the Pantanal wetland (2).

What are its uses?

Well, its stunning tree shape when in flower and exuberant pinkish-white flowering (1) make it highly recommended for landscaping in parks, gardens, and squares. Because its wood is heavy and soft, it is used for making tool handles and for internal construction (2).

And ...medicinal Properties?

There is both ethnobotanical and experimental evidence supporting the antimicrobial activity of T. roseo-alba bark for the treatment of infectious diseases (4,5) and of its leaves for inflammation-reduction activity (6).
