Cornflower 'Black Ball'
A hardy, easy to germinate flowering annual, sow seed from mid- autumn to early spring. Choose a position in full sun and direct sow. Cover with approx. 5mm of good garden soil or compost and water well. Seed should germinate within 7-14 days. Although drought hardy once established, regularly watering is required during germination and extended periods of dry. Thin seedlings as needed if planting becomes overcrowded.
