Attract butterflies and hummingbirds with this mildly fragrant sun lover. Toward summer's end, small white flowers appear in clusters atop 3' stems. Blooms are followed by attractive, 4" long seedpods that split open when ripe and release silvery-haired seeds. Quite showy when planted in masses-consider using to beautify slopes and ridges. Requires no care, once established.Asclepias incarnata
