Lathyrus latifolius, the perennial peavine, perennial pea, broad-leaved everlasting-pea, or just everlasting pea, is a robust, sprawling herbaceous perennial flowering plant in the pea family Fabaceae. It is native to Europe but is present on other continents, such as North America and Australia, where it is most often seen along roadsides.
Lathyrus latifolius can reproduce vegetatively from its taproot and rhizomes, or by reseeding.
It requires partial to full sun, and loam or clay-loam soil that is moist, mesic, or slightly dry. Unlike the related annual sweet pea, Lathyrus odoratus, with which it may be confused, it has no scent. While grown as a garden plant it may be pervasive and difficult to remove. Because of this, this species is often considered to be a weed despite its attractive appearance.
