Striped, ruffled petals on long stems.
From the Spencer Series. Lavender streaks throughout and lining the petal edge. Plants produce 3–4 blooms per 9–12" stem. Highly fragrant. NOTE: Spencer Series sweet peas are known as late-flowering because they require at least 12 hours of daylight, unlike more modern sweet pea varieties bred for winter production, which may require only 10–11 hours of daylight.

How to Grow:
DAYS TO GERMINATION:14-21 days at 55-65°F (13-18°C). To aid germination, seeds can be presoaked for 24 hours in room temperature water prior to planting.

SOWING:Transplant (recommended) - Sow 1/4- 1/2" deep into 72-cell flats or preferred deep-cell seedling container, 4-5 weeks before planting out. Darkness is required for germination. Direct seed - 6 weeks before last frost. Seedlings won't be damaged by light frost. Pinch when 6-8" tall to encourage denser branching and more flowers. Trellis support is required.
Support such as Hortonova vertical trellis is needed to support plants.

TIP:Using white on black plastic or straw mulch will help keep roots cool and the plants productive for a longer period.
