Wonderful flowers - like incurved chrysanthemums.
Sow March to April. Germinate at 20-30C (68-86F) on the surface of a good free draining, damp seed compost. Do not cover seed. Place in a propagator or seal container inside a polythene bag until after germination which usually takes 7-21 days. Do not exclude light at any stage, as this helps germination.
Seeds sown out of doors August/September should be sown in a sheltered reserve border or cold frame, pricked out to 15cm (6in) apart and planted in April where they are to flower. They can also be sown indoors and treated like half hardy annuals.
