Calotropis procera, also known as Apple of Sodom, is a member of the milkweed family. A native of parts of Africa and Asia, it’s another of the many invasive plants that have found a home in Hawaii. On the plus side, it’s a host plant for Monarch butterfly caterpillars, while the butterflies themselves feed on the flowers.
