Swamp Milkweed (Asclepias incarnata) is a herbaceous perennial native to wet regions of the eastern and central United States. Although they thrive in wet conditions, they also grow well in regularly irrigated landscapes. Swamp milkweed does not spread aggressively unlike other milkweeds.
You can expect Swamp milkweed to die back around Thanksgiving to return in the spring. It's a true favorite of butterflies, hummingbirds, bees, and other pollinators. It is a beautiful addition to any garden and makes an excellent cut flower.
Our milkweed is guaranteed Florida ecotype, pesticide free milkweed. They will most likely come with aphids and caterpillars but that’s why we do what we do! It’s grown to support our wildlife.
