What are the most beautiful, stunning, and lovely flowering plants that can be planted in tropical regions? I am starting a flower garden and I want only the best blooms that i can care for. What plant to buy?

Hibiscus and azaelas...bouganvillas(which can be invasive)...bouganvillias are happy being root bound and in pots....so watch planting them freely in your lawn unless you have plenty of room..and keep pruning them to keep under control...also night blooming jasmine is veryvery nice and flower at night..but you can smell the perfumed scent of the flowers for 2 or 3 blocks...
I lived in the Florida keys for 6 years, sub tropical...but all these plants I personally had..

Oh lucky you. I personally would plant hibiscus, they to me they are the most beautiful flower ever. They come in different colors. Here in this climate we can only grow them indoors and put them out in the summer.
