Lathyrus rotundifolius, the Persian everlasting pea, is a species of flowering plant in the pea family Fabaceae, native to Turkey. Growing to 1.5m (04.9feet) 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 -20C, but requires a position in full sun.
It holds the Royal Horticultural Society's Award of Garden Merit.[1] It is a suitable subject for scrambling over a fence or through another shrub or tree.
