Description
A hardy and eye-catching cottage garden annual, Cornflower Red Boy produces an abundance of double bright red flowers on tall plants. Easy to grow, like most cornflowers and tolerant of poor soil types.
| When to sow | March - April and September - October. |
| Where to sow | In early autumn surface-sow in trays of good seed compost and over-winter in a cold frame or greenhouse, thinning out and potting on as they grow. These can be planted out in spring and produce early flowers. Alternatively, shallow-sow directly into a well-prepared seedbed in spring, thinning out to 15cm. |
| What to do next | Water well until established |
| Once the cornflower have finished flowering, leave a few plants to die down and self seed. Others can be pulled up and composted. | |
| This plant will produce more flowers when grown in poor soils, so don’t over-fertilise. Pinching out the growing tips will encourage bushier growth. | |
| Flowering period | May to July |
