50 White Pearl Perennial Sweet Pea Seeds - Lathyrus latifolius White Flower for Garden Trellis

White Pearl Perennial Sweet Pea (Lathyrus latifolius) is a charming climbing vine prized for its clusters of pure white, pea-like flowers. Unlike annual sweet peas, this perennial species returns year after year, making it a reliable choice for long-term garden beauty. The delicate white blooms appear in summer and are excellent for cutting, attracting pollinators, and adding a soft, romantic touch to trellises, fences, and arbors.

This versatile vine is well-suited for cottage gardens, wildlife gardens, and vertical gardening. Its vigorous growth habit quickly covers supports, providing a lush green backdrop for the bright white flowers. White Pearl is a favorite among gardeners for its ease of care and ability to naturalize in suitable climates.

Planting & Care

Sow White Pearl Perennial Sweet Pea seeds indoors 6-8 weeks before the last frost or directly outdoors in spring after danger of frost has passed. Soak seeds in water for 24 hours before planting to improve germination. Plant seeds about 1/2 inch deep in a well-drained seed-starting mix. Keep the soil consistently moist but not waterlogged. Germination typically occurs in 14-21 days at temperatures around 65-70°F (18-21°C).

Once seedlings have developed several sets of true leaves, harden them off and transplant to the garden. Provide a trellis or other support for the vines to climb. Water regularly during the growing season, especially during dry spells. Mulch around the base to conserve moisture and suppress weeds. Perennial sweet peas are relatively low-maintenance and benefit from a light pruning after blooming to encourage bushier growth. In colder zones, apply a layer of mulch in winter to protect the roots.
