Sowing Instructions
| Sowing time: | spring |
| Sowing depth: | 1.5mm (1/16in) deep in a good seed sowing mix. |
Germination takes 5-10 days at 18-20C (65-70F).
They can also be sown outdoors in the spring where they are to flower, when the ground becomes workable, covering the seed to a depth of 3mm (1/8in).
Thin out the seedlings 39cm (12in) apart.
Alternatively, sow out of doors in the autumn for over-wintering in mild winter areas, when they will flower in late spring/early summer.
