Lathyrus rotundifolius, the Persian everlasting pea, is a species of flowering plant in the pea family Fabaceae, native to Iran. Growing to 1.5 m (4.9 ft) tall, this herbaceous perennial climber has twining, clinging tendrils and brick red flowers in summer. Unlike its relative, the sweet pea (Lathyrus odoratus), the flowers are unscented. It is hardy to −20 °C (−4 °F), but requires a position in full sun.
