Growing flowers surrounded by Georgia? I resently moved to Southern Georgia from Wisconsin. I want to plant...

I resently moved to Southern Georgia from Wisconsin. I want to plant flowers but am clueless as what to plant. I am only going to be living here for three years so i dont want anything expensive, but at duplicate time i dont want to replant moreflowers every year. What resonable priced perenials will grow in the sandy soil here? We hold really tall pine trees here, I ws thinking of planting something around the platform of the tree thats will climb the tree. I was wondering if a climbing rose could be planted at hand or if maybe i'll hold better luck with a humming bird vine. Im also wondering what would work best around hedge to dress them up. The only entry i can think of that would grow okay there is periwinkle since the soil is poor and rocky. I want to plant something arond the stub of the bird feeder also. Something that attracts butterflys and humming birds. I was thinking butterfly bush but that grows too soaring and wide. I have need of ideas on what to plant, and best time to plant. thankfulness

Sounds close to you've already done a lot of research. You may want to consider getting a landscaper designer to come give somebody a lift a look at the space as they'll be able to sustain you ID plants that will work in the specific locations, near the specific care, you've identified.
