Sow in trays or pots in a well drained seed raising mix.  Cover seed lightly with vermiculite after sowing. Keep evenly moist.  Germination should take 10-12 days at  20-21 °C. Transplant after 3-4 weeks to larger pots.  Grow on at 14-16 °C.  Callistephus do not grow temperatures below 8 °C and do not tolerate frost.
