How To Sow

Delivery

Reviews
Sow on the surface of the compost in late winter in John Innes Compost. Make sure that the compost is moist but not wet and seal in a polythene bag until after germination which usually takes 12-21 days at 15-21C (65-70F). Do not exclude light which is beneficial to germination.They can also be sown in mid summer, overwintered in a coldframe and planted out in spring. This produces larger plants.

Transplant when large enough to handle into 8cm (3in) pots and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost 38cm (15in) apart in well cultivated garden soil and some shelter.

  1. Closest to black yet

    By Peter Humphrey 20-07-2011

    I always try out seed for black flowers and invariably I am disappointed with the dark plum colours.I don't think I was ready for these.They are as close to black as is possible.The height of them and I have planted them in a group with dark chocolate sunflowers. I am amazed at how many compliments I have received. Well worth growing and an extremely good germination rate too!
