Milkweed in Florida
Florida holds a resident non-migratory monarch population in the south alongside migrants passing through the panhandle, and its native flora includes aquatic, pinewoods, largeflower and velvetleaf milkweed. Tropical milkweed is the state’s biggest monarch conservation problem, because it never dies back and OE parasite loads build to damaging levels.
The best milkweed to plant in Florida
Native to the state, garden-worthy and useful to monarchs. Start here if you are planting rather than identifying.

Rare or protected in part of this range: Curtiss’ Milkweed, Southern Milkweed. Do not collect seed or plants from wild populations of these species.
Not native but naturalised here: Balloon Plant, Tropical Milkweed, Giant Milkweed. Because Florida has mild winters, tropical milkweed can sustain year-round monarch breeding and raise OE parasite loads, so plant a native instead.
Planting milkweed in Florida
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.
Florida spans USDA zones 8a–11a, 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.
Where to buy milkweed in Florida
Start with Florida Native Plant Society. State native plant societies run the plant sales worth going to: locally grown, untreated stock, at a few dollars a plant, sold by people who can tell you where to put it.
