50 Heirloom Pastel Sweet Pea Seeds – Lathyrus odoratus

Heirloom Pastel Sweet Pea (Lathyrus odoratus) is a beloved climbing annual prized for its soft, pastel-toned blooms and intense, sweet fragrance. The delicate flowers in shades of pink, lavender, cream, and peach make this variety a favorite for cottage gardens, cut flower arrangements, and fragrant trellises. Sweet peas bring vertical interest and a romantic, old-fashioned charm to any garden space.

These heirloom seeds produce vigorous vines that climb readily on supports, blooming over a long season when kept picked. The more you cut, the more flowers you'll enjoy.

Planting & Care

For best results, nick or soak seeds for 24 hours before sowing to improve germination. Sow seeds indoors 4–6 weeks before the last frost, or direct sow outdoors in early spring once the soil can be worked. Plant seeds about 1 inch deep in a sunny location with well-drained soil. Provide a trellis or support for the vines to climb.

Keep the soil consistently moist during germination and establishment. Once seedlings are a few inches tall, thin to 6–12 inches apart. Water regularly, especially during dry spells, and mulch to retain moisture. Pinch out growing tips when plants are young to encourage bushier growth. Deadhead spent blooms regularly to prolong flowering. Sweet peas are cool-season annuals and may decline in intense summer heat.
