Lathyrus latifolius, the perennial peavine or perennial pea, is a flowering plant of the genus Lathyrus in the legume family Fabaceae. It is native to Europe but is present on other continents, such as North America, where it is an introduced species. It is a perennial plant and so grows and bloom every year without new seeds being planted. It is less strongly scented than the related annual sweet pea, Lathyrus odoratus. Peavines are sometimes grown as a garden plant but are pervasive and may be difficult to remove. Because of this, this species is often considered to be a weed despite its attractive appearance.
