Thank you! Gigi, I'm not sure hummers overwinter in Florida, do they? Some sites say they do, but most say they move on.
From
The University of Florida Extension:
Although some birds may stay in south Florida year-round, most winter in Mexico and South America. Males arrive in Florida in March. Females arrive about a week later.
And
Wild Birds Unlimited, also says that most will migrate across the Gulf.
If you mean a typical Mango tree, I'm not sure they attract hummers, but it might just because they're not around when they bloom. But I would think your mass of adeniums would attract them in summer. It's one of those things unless you're constantly watching for them, you might never notice them around.
