Looking to create a natural fence/border. Local nurseries seem to only have non-native.

I have a large front lawn on a corner lot and I’m wanting to grow a natural fence or border to keep the dogs in the area from walking up into it and leaving me “presents.” I also think it would provide habitat and look much nicer than a large grassy area.

Does anyone have and suggestions for what to use? I live in Mississippi and we often get periods of drought and then excessive rain in heavy soil. I’ve asked my local nursery and they recommended dystillium, which certainly seems to fit my needs. The only issue is that it’s not native. It’s not invasive either but I’d prefer native if I can help it.

Is there a suitable plant or should I go with the dystillium and then use natives inside the border since it’s more of a utility planting? I’ve tried googling but most results are ai generated articles and irrelevant stuff, and most gardening books I’ve seen are not focused on native planting.
