Sow thinly direct into finely raked, moist, warm soil where the plants are to flower at a depth of 13mm (½") raking in lightly. Germination takes 14-21 days. Choose a sunny position. Thin seedlings when large enough to handle with a final spacing of 30cm (12") between plants. Alternatively sow direct at a depth of 13mm (½") during September to stand the winter for flowering late spring the following year.
