An everlasting Sweet peas, Red Pearl, is a reliable, easy to grow perennial plant. It will scramble up trellis or through a shrub and give cut flowers all summer. Cut back in autumn and they will shoot up again in the spring. Being leguminous they provide nitrogen to the soil. Best in a well drained position against a trellis or wall in sun or part shade. Hardy perennial. I have soaked ten of these seeds overnight and they are now in a module tray.
Lathyrus latifolius, the perennial pea vine, perennial pea, broad-leaved everlasting-pea, or just everlasting pea, is a robust, sprawling perennial in the Pea Family Fabaceae. It is native to Europe but is present on other continents, such as North America and Australia, where it is most often seen along roadsides.
Lathyrus latifolius keeps its roots in a tidy clump, is easy to raise from seed, and is wonderfully fresh at a difficult time of year. Plant it next to something that dies down after midsummer or put it under a shrub and let it climb through the branches. It is best to sow indoors and put out when you get a strong plant.
