I saw these two small trees in my university campus and would like to know what they are so I can find out more about them.
If it will help, I can say that these are planted in Miami, FL. The pictures were taken in March. These are about 8 ft in height. I think they grow slowly because I've seen them at about the same size for a few years. They don't look like young trees to me, but that's really not saying much.
Identifying them would be a BIG help, but my next step would be to start learning about them online so any information on them will be very welcome as well.
Based on the answers, I realized I needed to post some more details. So I went back and got these closeups of the flowers and leaves. These are pictures of new and mature leaves and also the back of mature leaves. I removed the redundant pictures of the entire tree.
