Lathyrus rotundifolius

Lathyrus rotundifolius, the Persian everlasting pea, is a species of flowering plant in the pea family Fabaceae, native to Turkey. Growing to 1.5 m 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, but requires a position in full sun.

It holds the Royal Horticultural Society's Award of Garden Merit. It is a suitable subject for scrambling over a fence or through another shrub or tree.
