Lathyrus grandiflorus, two-flowered everlasting pea, is a species of flowering plant in the family Fabaceae, native to southern Europe. Growing to {{convert|2 |m|ft|abbr=on}} tall, it is a twining herbaceous perennial with grey-green leaves and, in late summer, bright magenta-pink flowers, the central keel a darker red. Unlike its cousin, the annual sweet pea (Lathyrus odoratus), it is unscented. Once established it is a robust plant with the ability to scramble into other shrubs and trees.{{cite web | url = https://www.telegraph.co.uk/gardening/howtogrow/3303338/How-to-grow-the-everlasting-pea.html | title = How to grow: the everlasting pea | author = Keen, Mary | date = 10 August 2002 | publisher = The Telegraph | accessdate = 19 March 2018}} It is very hardy, down to {{convert| -20|C|F|abbr=on}}, so is capable of surviving conditions in most temperate regions of the world.
