Spacing Plant out, 2 plants to a vertical support, 15cm (6in) apart in a mild spell in March-May.
Sowing, Seeds, Planting Sow October-December or January-March, 2 seeds into 1 rootrainer. When roots fill container, pot on 2 seedlings together into a 1 litre pot. Pinch out tips when plants have 4 pairs of leaves. If autumn sown, overwinter in a light, cool place. Sweet peas often have quite a hard seed coat so it may help to soften the seed before sowing. To do this, place the seeds on some damp kitchen paper and pop them in a warm spot. Once the seeds start to swell or sprout they are ready to sow. If the seeds don’t seem to be swelling you can try making a small nick in the seed coat (opposite the ‘eye’) as this will help moisture enter the seed and kick-start the germination process.
Care Tips Remove the climbing tendrils as they grow. Tie the stem into your framework on a regular basis. Can be grown in deep container pots up a climbing frame. Find out how to cordon train your sweet pea in Sarah's how-to guide.
Flowering May - August (winter-sown) or June - September (spring-sown), or 12-14 weeks from spring-sowing of seed.
Vase Life 4-5 days. Avoid direct sunlight and heat. This has a beautiful scent. Add a little sugar syrup to the flower water to extend vase life.

Very disappointed with these, colour was not as vibrant as I expected and flowers very small. Wont bother with these again.

Disappointing but could be due to late planting after delivery and insufficient water during hot weather

The most wonderful sweet pea - the colour is amazing as is the scent. My kitchen had been full of the delicious vibrant smell of sweet peas all summer long. It’s a shame it has to end! I look forward to next summer for a repeat performance!
