It is native to Europe but is present on other continents, such as North America and Australia, where it is an introduced species. Cultivation and habits 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. It is less strongly-scented than the related annual sweet pea, Lathyrus odoratus, with which it may be confused. 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. Culture Easily grown in average, medium moisture, well-drained soil in full sun. Tolerates some light shade. Also tolerates some drought. Best performance occurs in cool, fertile, humusy soils in cool summer climates with good air circulation. Provide even moisture and regular fertilizer throughout the growing season. Avoid overhead watering to the extent possible.
