Sweet Pea 'Parfume Promise' Seeds
'Promise' is a spectacular bi-colour Sweet Pea that brings a lively energy to the garden. It features large, wavy upper petals (standards) in a vibrant, rosy-pink, which contrast perfectly with the pure white lower petals (wings). It looks like a raspberry ripple ice cream in flower form.
This variety is part of the 'Spencer' family, meaning it has been bred for long, strong stems and large, frilly blooms, making it perfect for cutting. However, unlike many show varieties, it retains a lovely, sweet fragrance that captures the essence of a country summer.

🌿 Understanding the Plant
Sweet Peas are **Hardy Annuals**.
They live for one season but are tough enough to withstand a cold winter.
The Strategy: For exhibition-quality blooms on the longest stems, sow in Autumn (Oct/Nov) and overwinter them in a cold frame. For a relaxed, garden display, sow in Spring (Jan-March).
Top Tip: Sweet Peas are deep rooters. Sow them in "root trainers," deep pots, or even empty toilet roll tubes to give the roots plenty of vertical space to grow.
🌱 Growing Guide: How to Sow and Grow
Sweet Peas are hungry plants that thrive on rich soil and regular picking.
Germination:
Sow indoors in Oct/Nov or Jan-March. You can soak the seeds in tepid water for a few hours before sowing to soften the hard coat. Sow 1cm deep in moist compost. Keep cool (approx 15°C). Heat inhibits germination, so avoid hot propagators! Germination takes 10-21 days.
Where to Sow:
They need **full sun** and rich, fertile soil. Dig a trench and fill it with well-rotted manure or garden compost before planting out. Ensure you have a strong support structure (wigwam, trellis, or netting) ready for them to climb.
Care While Growing:
Tie them in: Use soft twine or sweet pea rings to guide the stems up the support.
Feed: Once flower buds appear, feed weekly with a high-potash fertiliser (tomato feed).
Pick, Pick, Pick! You must remove seed pods immediately. If the plant sets seed, it assumes its job is done and stops flowering.
