Pink trumpet tree, Savannah oak,

Often planted in parks and gardens. It has beautiful crown of pink flowers during the dry season and offers wonderful shade during the rainy season. 

"The tree crown is wide, with irregular, stratified ramification and only few thick branches. The bark can be gray to brown, in varying darkness and may be vertically fissured. Leaves are compound,digitate and deciduous. Each leaf has five leaflets of variable size, the middle one being the largest. Flowering occurs mainly in January and February, and is generally associated with dry periods; although flowering has also been observed in August, September, April and May. Flowers are large, in various tones of pink to purple, and appear while the tree has none, or very few, leaves. Pollination occurs probably by insects, although the flowers are visited by many birds such as tanagers, hummingbirds and orioles.
