This everlasting sweet pea is very easy to grow from seed and makes a perfect ground cover or climber.
Everlasting pea is a rhizomatous herbaceous long-lived perennial with trailing or climbing stems that produces attractive rose to white pea-like flowers over a long summer bloom.
Broadly-winged plant stems clad with oval, medium green, 3-inch leaflets in pairs will ramble indefinitely along the ground (foliage to 4-8\ tall) or climb by tendrils up nearby vegetation or support structures to 6-9' tall. Showy flowers (each to 1" across) in colors of rose, pink-purple or white bloom early summer to fall in racemes of 6-11 flowers. Flowers give way to flattened, pea-like seed pods. Both pods and seeds are toxic if ingested.
Easily grown in average, medium moisture, well-drained soil in full sun. Tolerates some light shade. Also tolerates some drought. Best performance occurs in cool, fertile soils in cool summer climates with good air circulation. Provide even moisture and regular fertilizer throughout the growing season. Avoid overhead watering to the extent possible. Plants spread by rhizomes and will easily self-seed to the point of being somewhat weedy and invasive.
Typical growing conditions are full or partial sun and a loam or clay-loam soil that is moist, or slightly dry. This plant is long-lived and can slowly spread. By the end of summer, the foliage becomes ragged and yellowish in appearance.
Soak the seeds in cold water for two hours before sowing speed germination. Sow to late winter to early spring ¼in deep in a good, free draining, seed compost. Make sure the compost is moist but not wet and seal in a polythene bag until after germination which usually takes 10-21 days at 55-65F. Any seeds that don't germinate after this period can be dug up lightly filed to make a small scratch on the seed coat and replanted.
