Vincetoxicum Hirundinaria - Perennial Plant, Vincetoxicum, Apocynaceae

Vincetoxicum hirundinaria 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). A perennial plant or simply perennial (Latin per, "through", annus, "year") is a plant that lives for more than two years. The term is often used to differentiate a plant from shorter lived annuals and biennials. The term is sometimes misused by commercial gardeners or horticulturalists to describe only herbaceous perennials. More correctly, woody plants like shrubs and trees are also perennials.
