Sowing – Sow outdoors where they are to flower. Prepare the ground well and rake to a fine tilth. Sow 20mm (¾in) deep, in rows 30cm (12in) apart. Thin out young plants to 23cm (9in) apart.
FOR SPRING FLOWERING: Sow seeds individually in 7.5cm (3in) pots and place on a warm windowsill or in a heated propagator at a temperature of 18-21°C (65-70°F), until after germination which usually takes 20-30 days.
