The yellow ipê is native to South America, where it is also known as guayacan or araguaney. It has a dark trunk, almost black, and very characteristic yellow flowers blooming before the leaves, resembling a jacaranda, but amber. The existing Yellow Ipê in the Alcázar is one of the few yellow specimens of this species in the city of Seville. In the American Garden, created for the Universal Exhibition of 1992 where the V centenary of the discovery of America was held, we can find pink ipês. For the design of the garden, on the banks of the Guadalquivir, the Roots Program was organized by which twenty American countries provided seedlings of 619 unique species of flora, including an ipê donated by Paraguay. Since then, the development of the Roots program has undergone several ups and downs that has been replaced by the action of citizen organizations like the one carried out by the Friends of the Garden of the Oliva. This association, among other duties, is spreading the biological heritage of the American garden among neighborhoods in need of the goodness of vegetation. An example of this patient and constant work is the garden of the association itself in the neighborhood of the Oliva cultivated for over 20 years and has formed more than 300 species, of which 50 come from seeds of the very same garden, among which there is one pink ipê probably originated in Paraguay. Friends of the Oliva reminds us that the gardens are grown, and have limits or not, they are fuzzy.
