Pearl White Everlasting Sweet Pea Seeds – Perennial Climbing Vine

White Flower Clusters on a Perennial Climber

Pearl White everlasting sweet pea (Lathyrus latifolius) brings clusters of pure white flowers and gray-green foliage to trellises, fences, and supported garden plantings. This vigorous perennial vine adds a soft cottage-garden look and can return in suitable growing conditions.

Let the stems climb a sunny support for a fresh white display, then cut a few flower clusters for a vase indoors. Unlike annual sweet peas, everlasting sweet pea flowers are unscented.

Sowing and Germination

Everlasting sweet pea seeds have hard coats. Gently scarify a small area of the coat without damaging the inner seed, then soak overnight in tepid water before sowing.

• Sowing: Direct sow outdoors after frost danger has passed into a weed-free, well-drained seedbed
• Depth: Approximately 1/2 inch; cover the seeds
• Germination temperature: Approximately 64–68°F
• Typical germination: 14–21 days, depending on conditions and seed preparation
• Moisture: Keep the seedbed evenly moist without waterlogging

Thin seedlings to provide room for growth and airflow. Install a trellis, netting, or wire support early so developing stems have something to climb.

Growing Care

Water regularly while plants establish and during dry periods. Remove faded flowers before pods mature to reduce unwanted self-seeding. Give this vigorous vine space and guide its growth to keep it from overwhelming neighboring plants.

Cut back dead stems in winter or early spring. Flowering season, mature size, and winter survival depend on climate and growing conditions.

Cut-Flower Tips

Harvest fresh flower clusters in the cool morning. Place stems promptly in clean water and remove foliage that would sit below the waterline. Enjoy their white color and form without expecting the fragrance of annual sweet peas.

Important: Ornamental Only

Everlasting sweet peas are not edible garden peas. Seeds and pods are toxic if eaten. Do not consume any part of the plant, and keep seeds and plants away from children and pets.
