The Cornflower is a slender plant of great charm, indigenous to Europe, today they are rare in the wild, they flourish instead in gardens.
They are the most splendid of annuals. Breathtaking when they're grown in dense drifts, they are easy to grow, they flower all summer, make great cut flowers and butterflies and bees adore them.
The other advantage is that they're a hardy annual, which means they can be sown late in autumn or very early in the spring. The seedlings have time to establish before frost sets in. They will develop strong roots during the cool months, allowing them to form bigger plants and to flower six weeks earlier.
When we think of cornflowers, we imagine running through vast fields of them, but you don't need a huge area to grow them, in fact they can be easily grown in containers.

Sowing: Sow in August to September for early summer flowering the next year or sow directly where they are to flower in March to April.
Sow thinly, 3mm (1/8in) deep in drills 30cm (12in) apart in well-cultivated soil which has been raked to a fine tilth. Water ground regularly, especially in dry periods.
When large enough to handle, thin out seedlings to 15cm (6in) apart
Sow in pots or trays of moist seed compost and cover with a very fine sprinkling of compost or vermiculite. After sowing, do not exclude light as this helps germination. Keep at 15 to 20*C (59 to 68*F). Keep the surface of the compost moist but not waterlogged. Germination will usually take 14 to 21 days.
When they are large enough to handle, transplant the seedlings into 7cm (3in) pots or trays. Overwinter plants in cool, light, frost-free conditions before planting out the following spring, or grow on as greenhouse pot plants.
This fully hardy plant requires a sunny site, growing in most well-drained soil types, even poor soil.
Do not over fertilise because this will lead to excessive leaf growth at the expense of blossoms. Cornflowers bloom more when crowded.
The wiry plants may need some discreet support, and deadheading helps to prolong the flowering season.
