Also called Green Antelophorn. Attracts Monarch butterflies and a host of other insects. Very tolerant of dry conditions, Spider Milkweed can be found in sand prairies, pastures, and even ditches. Because of its shorter height and taproot, Spider Milkweed does not tolerate high amounts of vegetative competition. Spider Milkweed features rose-white flowers surrounded by green that form in showy clusters, often one per plant.
