Thompson & Morgan is delighted to work alongside the Royal Botanic Gardens, Kew to offer special seed collections to home gardeners. This Kew Pollinators Collection has been specially selected by The Royal Botanic Gardens, Kew.
Lathyrus latifolius is a charming perennial Sweet Pea which returns year after year. The purple-pink flowers are unscented, and may not be quite as showy as its annual cousins, but this resilient species will happily ramble about without becoming a nuisance in perennial borders. Ideal for decorating evergreen shrubs with a splash of colour, or sprawling down tricky slopes and embankments as quick-growing summer ground cover. Height: 200cm (79"). Spread: 100cm (39").
1 packet (10 sweet pea seeds) (KB7574)
Sow sweet pea seeds indoors in October for transplanting outdoors in spring, or direct sow outdoors from March to April.
For autumn sowings autumn, sow 3 seeds per 7.5cm (3") pot at a depth of 1cm (½") in free-draining, seed sowing compost. Place in a propagator or seal container inside a plastic bag at a temperature of 18-20C (65-70F) until germination which takes 7-21 days. Once germinated, grow sweet peas on in cooler conditions, before transferring to a cold frame for overwintering. Spring sowings can be made outdoors directly into drills at a depth of 2.5cm (1"), and a distance of 7.5cm (3") apart. Pinch out the growing points of each stem once the second pair of leaves has opened to encourage bushier growth.
In spring, plant out sweet peas at a distance of 23cm (9") apart in any well drained garden soil in full sun.
Feed and water Lathyrus plants regularly throughout the growing season. Deadhead faded blooms to prevent seedpods developing. This will encourage more blooms to be produced and extend the flowering period throughout summer. Cut back old stems to ground level when they begin yellow in autumn.
