What are the best garden plants for South Louisiana?

Hello friends,

I am horrible at gardening, but I want to have a small garden in my homestay / Bed and Breakfast. I live in Southern Louisiana and the front yard gets sun for a large portion of the day. Everything I try putting there dies, no matter how well I take care of it.

I am busy hosting guests so I want something that will look good but doesn’t require too much work. I know I have to weed and water, but I don’t want to, nor do I have time to be in my garden all the time. Suggestions?
