These attractive, bright yellow flowers once commonly seen in cornfields across the British Isles. Nowadays they are only occasionally seen on waste ground, but you can change this by adding these to your wild garden. Height: 45-60cm.
Sow outdoors where they are to flower. Prepare the ground well and rake to a fine tilth before sowing. Sow 6mm deep, in rows 30cm apart. When large enough to handle, thin out seedlings to 15cm apart.
