Agrostemma githago 'Ocean Pearl' - SeedsCorn Cockle

Direct sow Agrostemma seeds outdoors where they are to grow from March to May. Choose a position in full sun on well drained soil which has been raked to a fine tilth. Sow seeds thinly, at a depth of 12mm (1/2") in drills spaced 30cm (12") apart and cover the seed with its own depth of soil to exclude light. Water the ground regularly, especially during dry periods. Germination usually takes 7 - 14 days. When corn cockle seedlings are large enough to handle, thin them out to 30cm (12") apart.

Alternatively, sow outdoors in late summer. Corn Cockle plants will develop and overwinter to make strong plants for flowering the following May and June.
