Agree with Ben, good chance it's a delonix regia also known as red flame tree and often wrongly called a jacaranda. A possibly boring fact about the delonix regia is that it is a legume but it doesn't fix nitrogen, I believe the only example of a non nitrogen fixing legume known to mankind. You could dig the
roots and if you find N fixing nodules you know it ISNT a D Regia.
This tree is definitely some kind of legume tree in the
Pea family. I tend towards D regia due to the leaf shape which is slightly different and more regular than other similar trees such as acacia, palo verde, mesquite and Leucaena Leucocephala.Also the others mentioned will flower when only months old and knee high, whilst the D Regia can take longer to reach flowering age.
