|discussion=<p>Asclepias variegata and the following species (A. exaltata, A. purpurascens, and A. quadrifolia) inhabit deciduous forest understories in eastern North America and often co-occur. Asclepias variegata has showy, snowball-like spheres of bright white flowers. On closer examination, the staminal column of each flower is colored reddish purple, forming a neat belt between the corona and corolla. Non-flowering specimens have been confused with A. purpurascens. The leaves of A. variegata have a thicker texture, and the blade apices are broader and more rounded than in A. purpurascens. Asclepias variegata has suffered serious declines at the northeastern margin of its range and is reported to have been extirpated from Ontario and Connecticut. In addition, it is considered to be of conservation concern in Delaware, New Jersey, New York, and Pennsylvania.</p>
