An increasingly popular cottage garden and border plant now available from seed in this exclusive designer mixture. Only large flowered, border varieties have been selected in shades of blue, purple, pink and white, including 'Splish Splash'T, a striking blue and white bicolour. Without doubt the cheapest way to grow a wonderful range of colours. Flowers early to mid summer. Heights range from 30-60cm (12-24in).
Sow from February to late June in a good free-draining seed compost just covering the seed with compost or vermiculite. Make sure the compost is moist but not wet and seal inside a polythene bag. Leave at a temperature of 13-15C (55-60F). If no germination has occurred after 4-6 weeks, place in a refrigerator for 3-6 weeks. During this period observe regularly and remove from the fridge if the seeds start to germinate. After 3-6 weeks return to 13-15C (55-60F).
Cutting back old flowering stems keeps the plants tidy and often encourages a further flush of flowers.
