I agree with Porkpal, be very careful about wild roses. There are about 10 species of wild roses recorded in Mississippi and only 3 are listed as native. At least two of those exotics are very invasive, Rosa bracteata (McCartney Rose) and Rosa multiflora, others may be invasive also. Here are the 3 listed as native,
Rosa carolina, Rosa palustris and Rosa setigera. You should be able to find them for sale online.
