Heirloom Mix Sweet Pea Seeds – Fragrant Climbing Annual

Old-Fashioned Sweet Peas for Fragrance and Color

Bring cottage-garden charm to a trellis or fence with Heirloom Mix sweet peas (Lathyrus odoratus). This climbing annual mix offers fragrant flowers in shades of lavender, pink, purple, red, salmon, and white, with stems suited to fresh-cut bouquets.

Train the vines beside a seating area to enjoy their fragrance outdoors, then gather a few blossoms for a small vase indoors. The mixed colors create a relaxed, romantic display; the balance of shades varies between plants and packets.

Sowing and Germination

Sweet peas grow best in cool weather. Direct-sow in early spring when the ground can be worked, or sow in fall in mild-winter climates. Soak seeds for several hours or overnight before sowing to soften their hard coats.

• Sowing depth: Approximately 1/2 inch
• Germination temperature: Approximately 64–68°F
• Typical germination: 14–21 days, depending on conditions
• Moisture: Keep the seedbed evenly moist without waterlogging

For indoor starts, use individual deep pots and transplant gently to minimize root disturbance. Acclimate seedlings gradually to outdoor conditions. Provide netting, strings, or a trellis early so vines have support as they grow.

Growing Care

Water regularly during establishment and dry spells. Mulch around established plants to help conserve soil moisture. Pinch young growing tips to encourage branching, and watch young seedlings for slug and bird damage.

Pick flowers frequently and remove spent blooms before seedpods form to encourage continued flowering. Bloom timing and duration vary with sowing date and climate; prolonged summer heat can shorten the display.

Cut-Flower Tips

Cut stems in the cool morning when the lower blossoms begin opening. Place promptly in clean water and remove any foliage below the waterline.

Important: Ornamental Only

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.
