Milkweed: Showy (Asclepias speciosa)
Milkweed: Swamp (Asclepias incarnata)
As the name indicates, these swamp milkweed seeds for sale thrive in swamps and low meadows or along streams. The bright pink flowers attract swarms of bees and butterflies, and have a sweet scent described as similar to vanilla or cinnamon. At one time, the silk from swamp milkweed seed pods was spun for fabric or used for stuffing pillows; in World War II, school children gathered the silk to provide a cheap filling for soldiers' life jackets. Commercial attempts to make use of this abundant plant included the manufacture of paper, fabric, lubricant, fuel, and rubber; eventually these became impractical and were abandoned. Though this plant is toxic to most animals, butterflies are immune to the plant's poison and actually become rather poisonous themselves as protection from predators.
