I live in Georgia (south of the center), and it's not quite like you describe. The main crops in this area are cotton, peanuts, and pecan trees. I believe what my bees eat off of mostly are flowering trees, flowers (wild and part of home landscaping), and wild black berries. The people around here are big on pretty landscaping. It's not as prominant as the famous roses of Tyler Texas, but pretty all the same. I have no idea of the average rain fall, but it is often rainy. Often I feel we live in a rain forest, then other times it'll just be perfect outside - a nice temp, not too humid, but everything is lush and green.
To try to give you a picture of what it's like...... think of first a pine forest, add within that forest maples & oak mostly, with ferns and wild black berries as a thick undergrowth, PLUS honeysuckle & really thick vining plants (with a type of trumpet flower on it) growing on everything it can reach (up trees and phone poles - clumping across phone lines - and in some areas turning the forest into a mass of vine). The vine is called Kudzu, and looks like this:
But here's what an accessable area of the woods looks like (not my back yard, but looks just like parts of our 21 acres):
Another common Georgia forest scene. And if you are silly enough to decide to hike in these forests with a fog like that, expect to come out with a minimum of 100 mesquito bites:
And people landscape there yards with all these types of plants shown in this picture:
And this plant has taken over many parts of the landscape. It's also a vining plant, called wisteria:
I hope I didn't overwhelm you with pics, but I find it to be the best way to really show something.
It can get cold here in the winter, and might snow once every 10 years. But for the most part the weather is mild. We have flowers blooming in our yard year round. My first year I harvested some honey on my daughters birthday in Febuary, and had my hive swarm mid-march. This was from a hive I'd started at the end of June the summer before. I'm hoping to make one more hive this year from the extra bees in my three hives. I feel I really need to, or else all three hives might swarm early next spring.
I was hoping to sell my honey, but really don't seem to be finding the people to buy it. I tell just about everyone that I have hives, and no one ever says "I'd love some honey, do you sell it?"
