This choice plant will grace any border with its shimmering sprays of regal mauve with attractive creamy-yellow stamens. Ideal for cutting. Height: 120-150cm (4-5ft).

Sow spring to mid-summer in a good seed compost just covering the seed with compost. Germination can take from 1-3 months at 15-21C (60-70F). If germination has not started after 8 weeks they can be pre-chilled which often speeds up germination. To do this seal in a polythene bag, place in a refrigerator 3-5C (37-41 F) for 3 weeks then return to warmth 15-21C (60-75F). Inspect regularly and remove if any start to germinate in the fridge. Seed sown early will often produce flowers the same season.

Transplant when large enough to handle into 7.5cm (3in) pots. Move to a coldframe or plunge the pots up to their rims in a sheltered site outdoors and plant out in autumn 30cm (12in) apart in a rich moist, well drained soil, sun or part shade.
