Excellent architectural border plant for autumn flowering, producing lots of deep red stems crowned with panicles of wine red flowers. Height: 120-150cm (4-5ft).
Sow from January to late June, early sowings will flower the same season. Sow on the surface of a good seed compost and just cover the seed with a thin layer of compost or vermiculite. Make sure the compost is moist but not wet and seal inside a polythene bag until after germination which usually takes 21-40 days at 18-24C (65-75F). To speed this up place in a fridge, after sealing in the polythene bag, and leave at 3-5C (37-41 F) for 2-3 weeks, then place in warmth, inspect regularly while in the fridge and remove immediately if they start to germinate.
