Hi, I am new to permaculture and located in central Arkansas as well. I have a bit of land in the country that I would like to create a food forest on but have not been very successful in finding types of plants from this area to use. Perhaps some of you could suggest some interesting types of nitrogen fixing trees to use. I have currently some red buds and access to get mimosas. Not sure if I want to use locusts trees or not. What would some other good choices be for Arkansas?
