Green milkweed (Asclepias viridis)

Green milkweed (Asclepias viridis) is a perennial herb found in the southeastern and south-central regions of the United States. This plant features green flowers and, like other species of milkweed, exudes a thick, milky white sap when its stems or leaves are cut. Monarch butterflies commonly use milkweeds, including green milkweed, as host plants for laying their eggs.
