Oh, fun topic! Floriculture is my specialty, but if I was looking for something new and had a 1-acre farm I would probably start a U-pick operation. I'd start with blackberries, raspberries, and strawberries because they mature and begin setting fruit quickly. I might add blueberries, if the market was right. I'd probably start some hives as well since the bees would help with pollination and easy nectar would support the hives.
