Vincetoxicum hirundinaria, commonly named white swallow-wort (its seedpods are reminiscent of a swallow's wing, or tail), is a long-lived herbaceous perennial of the genus Vincetoxicum in the family Apocynaceae. It is native to cliffs and slopes, especially in calcareous soils, of continental Eurasia (including some Baltic islands). There are introduced populations in North America (Ontario, Michigan, and New York).
