Tur­quoise Lagoon

Sweet Pea Seeds

Turquoise Lagoon sweet pea produces copious delicate, sweetly fragrant rosy pink blossoms that mature through lavender to a uniquely tropical aqua blue.

Developed from the crossing of Lathyrus odoratus with another species of sweet pea, L. belinensis, Turquoise Lagoon is part of a new category of sweet peas known as shifters. Flowers open in one color and change color as they age on the plant or as cut flowers in the vase, putting on a spectacular display.

Vines grow 4-6 feet high. Turquoise Lagoon sweet pea is truly a feast for the senses!

Growing Tur­quoise Lagoon Sweet Pea Seeds

Bee introduces how to plant

Plant Sweet Pea Seeds: Start seeds in winter or early spring, about 6 to 8 weeks before your last frost date. Prior to sowing, nick the outer seed coating with nail clippers or soak in water for 6 to 8 hours to allow for faster hydration and improved germination. Sow in 4 in. pots, using a seed starting mix, with 2 to 3 seeds per pot. Sow seeds ½ to 1 in. deep, keep out of direct sun. Once germination occurs, provide direct light. With soil temperature kept at 55 to 65°F, germination is in 7 to 21 days. Thin seedlings down to 1 per container about 1 week after germination. Transplant into the garden once soil can be worked and seedlings have 2 to 3 sets of leaves. In mild climates, seeds can be directly sown in fall. Plants grow best with 6 to 12 in. spacing.

Grow Sweet Peas: Full sun to part shade. Rich, moist, well-drained soil. Protect young seedlings from slugs, snails and birds. For fuller plants, pinch or cut back seedlings when there are 3 to 4 sets of leaves. To promote a longer bloom season, deadhead frequently.
