My favourite pale sweet peas, in beautiful, delicate colours.

The seed packet contains a mix of all three old-fashioned, highly scented varieties: The seedling collection includes 4 or 8 seedlings each of:
Genus Lathyrus
Group/Species odoratus
Type Hardy Annual, Hardy Annual Climber
Common Name Sweet Pea
Border Position Climber
Soil Type Fertile, Neutral
Scent Scented
Site Full Sun
Moisture Moist but Well-drained
Height 2m (6ft 6in)
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 - September
Vase Life 4-5 days. Avoid direct sunlight and heat. This has a beautiful scent.
Harvesting Keep picking as often as you can.

This is the third year running I have bought your sweet pea seedlings and have always been successful. Though some times I think I don't deserve to be, I am not always very attentive but they don't seem to mind.

Did not grow very well when seedlings planted in the garden and eventually died off.

The packaging was excellent, the young plants were very healthy and all three varieties in this mix are now flowering. 'Anniversary' is stunning - it has large frilled flowers with long stems. 'Mrs Collier' is also lovely - unusually, it's cream rather than white and has velvety flowers and long straight stems. 'Painted Lady' is very disappointing, though - the stems are far too short (sometimes just 2-3cm) and the flowers are small and underwhelming. I've planted this collection with two other varieties (Prince Edward of York and Blue Velvet) so the overall effect on an arch is good. But if I was relying only on this collection of three varieties for colour and cutting, I would have been very disappointed.

Plants were healthy and started flowering early and were nicely formed, however the stems of the sweet pea flowers were no length at all some 3" some 4". Previously I had grown from seed and the stems were much longer. Not sure if this was something that I had done or not.

Reply from the Sarah Raven Team:

"Thank you for your review. We have found Sweet Pea stems to be shorter in general this year due to the unusually hot weather, meaning the plants 'hurried' their flowering, resulting in shorter stems."

Some of the plants did much better than others - I don't know why - but after a rather slow start they flowered very well and I was cutting flowers every day.

I bought a whole bunch of plug plants and tubers in Spring, all for a clients cutting garden. I grew the plant on until they were 2/3Litre pot size. The plants were all good, strong and sturdy and I only have two that died off in around 275 plants. I was dissappointed with the dahlias though as the not all came true as per the label. I certainly didnt get the Labyrinth that I ordered.

Seedlings arrived in pristine condition but it has been a disappointing year for sweet peas as far as I was concerned. No reflection on the quality of the product they did not like the south facing constant heat. That I guess is gardening for you. Your dahlias on the other hand continue to be magnificent.
