Sowing Information:
Sow outdoors from spring to early summer or in the autumn for flowering the next season. Prepare the ground well, when it becomes workable by raking to a fine tilth and sow 1.5mm ( in) deep in rows 30cm (12in) apart.
Growing Information:
They prefer a sunny site in ordinary well drained soil but will flourish in most sites and soils. Thin out the young plants to 30cm (12in) apart when the seedlings are large enough to handle. Seed sown in autumn will flower in early summer and staggered sowings through spring will extend the flowering season.
