Importance to wildlife:
Similar species (if any): Asclepias viridiflora has a slight resemblance to Asclepias meadii (Mead's Milkweed), but the latter has flowers that are broader and have horns, and this species is rare and believed extirpated in Wisconsin. Asclepias hirtella (Prairie Milkweed) also has a resemblance, but it has inflorescences that are fairly dense with flowers and more narrow shaped leaves compared with A. viridiflora.
Ethnobotany: No recorded uses by tribes from Wisconsin. The Blackfoot used this plant for several medicinal purposes including as an antirheumatic, dermatological aid, eye medicine, pediatric aid, and throat aid, and they also used this species as a food source. The Lakota employed the plant as an antidiarrheal, gynecological aid, and a pediatric aid (Moerman, p. 110, 1998).
