Corncockle (Agrostemma githago)
The corncockle or corn campion is now almost extinct in the wild such that it is a protected species. It has jewel-like flowers of cerise-pink on long single stems from June to August. It is tall so needs to be grown through other plants or with species such as field poppies, cornflowers and corn marigolds for support. Large black seeds produced in summer are not eaten by birds and are heavy so drop close to the parent plant for next year's show. Ht 1-4ft. Grow in a sunny spot. Harmful if eaten. Supplied in trays of 6 for £3.50.
