Though not as well known as other varieties of milkweed, Tall Green Milkweed distinguishes itself with abundant clusters of green-white flowers that attract many butterflies and bees. This species has been classified as threatened in some states, since its natural habitat is decreasing. It can still be found occasionally growing in dry prairies, rocky areas, sandy wetlands, or along roadsides. At one time, the silk from this plantís 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 soldiersí 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 plantís poison and actually become rather poisonous themselves as protection from predators.
