That means if there is no Milkweed, there would be no Monarchs :( It is also an important nectar plant for bees and other insects. The common name Milkweed was given to this plant because of its milky juice. The scientific name comes from Asclepius, the Greek god of healing, because of the many folk-medicinal uses for the milkweed plants. The dried seed pods are also very interesting for dried arrangements.
