what kind of plant is this?

Hi! I am curently living in Trinidda and Tobago. This is a bush thta I have in my garden. My gardener trims it regularly to give it  a nice shape.  I noticed thta bush had flowering buds and started to give it a flowering food . So now it is blooming like crazy. Many people asked me what kind of plant is this?  and I have no idea. Looked a lot on line but mot much luck so far. Does anyone knows what is this or may be what family plant is this one? Would be very greatful for any info.
