Eyecatching and unique, this annual Lathyrus species is the only yellow sweet pea you'll find. The small, unscented, acid yellow flowers are produced on vigorous stems against a backdrop of soft green foliage throughout midsummer. Lathyrus chloranthus 'Lemonade' makes a striking feature and a real talking point. Perfect for patio containers or growing as an annual hedge or screen. Height: 150cm (59"). Spread: 30cm (12").
Sow sweet pea seeds indoors in October for transplanting outdoors in spring, or direct sow outdoors from March to April.
In 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 20-25C (68-77F) until germination which takes 10-21 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 sweet peas outdoors at a distance of 23cm (9") apart in any well drained garden soil in full sun. Train the stems onto a suitable support such as trellis or a free standing climbing frame. Try using our sweet pea support rings to tie the stems to their growing supports while they become established.
