Description
Sweet Pea 'Turquoise Lagoon' has been produced by the same breeder as ‘Blue Shift’ and is certainly just as striking. The delicate pink blooms mature to a vibrant turquoise, producing a stunning display of shifting colour. It also makes a great cut flower as the blooms even change colour in the vase after being cut. A true ‘must-have’ variety for sweet-pea admirers that is sure to attract envious glances from neighbours. 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 (1/2") 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 out sweet peas 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. Caution: Seeds are harmful if eaten.
