About

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.

How to grow it

Lathyrus latifolius is a perennial herbaceous vine (climber), which can reach 6 feet or more by means of twining tendrils, but in open areas sprawls. It is frost-hardy, long-lived, and slowly spreading. The foliage becomes rather ragged and yellowish by the end of summer.

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.
