A high quality mixture in shades of rose, pink, blue and purple, with grey-green foliage. Superb for containers and bedding with compact, neat habit and flowering only 16-20 weeks after sowing. Flowers summer. Height 30cm (12in).

Sowing Instructions

Sow in February/March for flowering the same year or in August for overwintering. Use a good seed compost and just cover the seed with a thin layer of compost or Sow-Lite (vermiculite). Germination takes 14-30 days at 15-18C (60-65F). Don't exclude light, sealing in a polythene bag after sowing is helpful.

Aftercare

August sown plants should be overwintered in a cold frame/ greenhouse etc for planting out the following spring. The flowers are excellent for cutting and last well in water.
