Handroanthusimpetiginosus (Mart. ex DC.) Mattos“Ipê roxo”, “ipê rosa” or “pink lapacho”“Ipê roxo is a common name for Handroanthusimpeginosus. “Ipê” is a tupi[1] word that main “thick bark tree” and “roxo” is a Brazilian word for purple. Even the flowers being pink the most common name for the tree is purple ipê. The group of Ipês are broadly used in urban landscape because the flower period is so exuberant, the plant is resistant to dry soils and urban conditions. Nowadays, there are more than 100 different ipês species with different colours, shapes and sizes. The 4 main colours are yellow, purple, pink and white. I particularly love the Handroanthusimpeginosus because the inflorescence form looks like a beautiful flowery ball” Suzy’s opinions.TheHandroanthus impetiginosus is a native tree of Brazil, but it is not endemic and occurs in almost all South America and Central America (Flora do Brasil 2020). In Brazil, the purple ipê occurs in almost all territory. The Figure 1 shows where the plant occurs in Brazil, being North in green, Northeast in orange, Central-west in yellow and blue; and Southeast in red, the only region of Brazil that the ipês are not present is in the south.Figure 1.

Except in frost-free inner-city areas or coastal extremities requires glasshouse conditions. Can be grown outside once risk of frost is over (most succulents, many subtropical plants, annual bedding plants, many spring-sown vegetables).10b Temperature (?C): (30) – (70) (Figure 3).Temperature (?F): (- 1.1) – (21.1) (Figure 3). Figure 3.

While the spread in general is between 10 – 12 m but into closed forest can be up to 25 m. FloweringPeriodThe tree presents two or more flowering flows for keep the tree flowering for more time. This happened because the flower buds bloom gradually, so, when some flowers are dropping another flowers are blooming (Salomão & Camillo, 2016). Each flowering flow remains about 10 days and drop on the floor, so with multiple flows is possible keep the tree flowered for a whole month or more. This massive flowering is a tree strategy to grab pollinator’s attention even by far of it (Schlindwein et al., 2014). In Brazil, the flowering period occurs in different times in each state as shows in Table 2.Table 2.

So, the tree present two stages: vegetative stage, with leaves and completely green (Figure 4) and a reprodutive stage coverd with pink-purple flowers (Figure 5). During the flowering period the tree higlight between other trees.
