A beautiful, magenta-purple annual wildflower, once a common sight in cornfields. Performing best in poor, well-drained soil, the flowers are highly attractive to bees. Self-seeds readily. Ht
Sow indoors in early spring, at 13-18*C (55-65*F) 4-8 weeks before planting outside, alternatively, the seed can also be sown directly where they are to flower in mid to late spring.
Use well drained compost and cover to a depth of 3mm (1/8in). When large enough to handle, transplant the seedlings into small pots to grow on. Acclimatise to outdoor conditions for 10-15 days before
planting out after all risk of frost. Plant 15cm (6in) apart.
Deadhead regularly to prolong flowering. In autumn cut the faded flowerheads down to the ground, but leave a few plants to self seed.
