Chigger flower is a common name for various plants, including members of the genus Asclepias. These plants are also known as milkweeds, due to the milky sap that flows from their stems. Additionally, they are sometimes called butterfly weed, because they are attractive to butterflies and other pollinators. Other synonyms for chigger flower include orange milkweed, tuberosa, pleurisy root, and silkweed. These plants are native to North America and grow in open, sunny fields and meadows. They are prized for their striking orange and yellow blooms, which appear in mid-summer and continue for several weeks. The plants are easy to grow from seed and provide important habitat and food for many species of wildlife.
