Not native but naturalised here: Balloon Plant, Tropical Milkweed. Because Mississippi has mild winters, tropical milkweed can sustain year-round monarch breeding and raise OE parasite loads, so plant a native instead.
Planting milkweed in Mississippi
Sow seed outdoors in November to January. Winter then supplies the cold-moist stratification most milkweed seed needs, and germination happens naturally as the soil warms. If you have missed that window, chill seed in the refrigerator for 30 days and sow after your last frost. The full method is here.
Mississippi spans USDA zones 7b–9a, so check the zone range on each species page before committing. Match the species to your site rather than the other way round: dry, sunny and poor suits butterfly weed and the whorled species; a damp spot suits swamp milkweed; shade suits very few milkweeds at all.
Plant at least ten stems in one group rather than scattering them, because female monarchs find dense patches far more readily. Add late-season nectar such as goldenrod and asters so the fall migratory generation has fuel as well as host plants. How to lay out a monarch garden.
