Genus Lathyrus

Common Name Sweet Pea
Border Position Climber
Soil Type Acid, Alkaline, Chalky, Clay, Fertile, Neutral, Sandy
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 April-May.
Sowing, Seeds, Planting Sow October-December or January-April, 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 a hard seed coat so it may help to soften the seed before sowing. Do this by placing seeds on damp kitchen paper and putting somewhere warm until seeds swell or sprout. You can also make a small nick in the seed coat to help moisture enter the seed before sowing.
Care Tips Tie the stem into your framework on a regular basis and pick pick, pick. If you have the time, remove the climbing tendrils as they grow. 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.
Harvesting Keep picking as often as you can.
