Blueberries can be grown in containers but you will need two different cultivars which will mean at least two containers. Also be sure to select blueberries suited for the south. I think you will find the amount of berries they produce will not compensate for the container space they take up.
Water is necessary of course but also vegetables/fruits grown in containers also require diligent fertilization.
I would also suggest that you will find the best time to grow carrots will be while the temps are still cool. I have some growing in a raised bed right now. They shake off frost easily but do not seem to produce well in the heat of summer.
Shop through the different seed catalogues as many have a section for container grown plants. Perhaps you might want to select the seed specifically for the small plant size or small fruit/vegetable size. Either way, container gardening is rewarding. Should you grow cucumbers or other vining plants, you can easily use a trellis to grow them upward.
This link is just one site that has a selection of flowers and vegetables suited to container culture.
