Blue boi seeds

Timing
Direct sow starting just before last frost, and again every two weeks until end of spring. Centaurea can be direct sown in autumn as well. Starting indoors is not necessary, but can be accomplished by keeping seed trays in the dark at the optimal soil temperature of 15-21°C (60-70°F). Move under bright lights once germination occurs, and transplant out in late spring, after all risk of frost has passed.

Other Uses:
Cornflowers are prized historically for their blue pigment. Cornflowers are often used as an ingredient in tea and is famous in the Lady Grey blend of Twinings.

Sowing Indoors:
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 15-20°C (59-68°F). Keep the surface of the compost moist but not waterlogged. Germination will usually take 14-21 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.

Centaurea cyanus ‘Blue Boy’ is a very fine, old, tall variety, a double flowered cultivar of the wildflower form, with lance shaped, long and graceful leaves. The upper half of the plant has multiple stems which produce many flowers from early summer until frost.
The Boy series, also known as the Ball series, feature double flowered blooms on tall stems for garden or cutting, are available in many colours including Black, Blue, Pink, Red and White.

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

A favorite annual flower and cottage garden staple, a single cornflower looks like a burst of fireworks. The piercing, bright blue flowers with ruffled petals and violet-blue centres appear from early to late summer.
These beauties grow well as border plants and are wonderful in a cutting garden; they look fabulous clustered among other contrasting flowers such as pink roses.

Nomenclature:
Once upon a time anything that grew and bloomed in a grain field was considered a ‘cornflower.’ As time passed, that moniker stuck to Centaurea cyanus in particular, all the other flowers left to find their own names.
Bachelor’s-buttons, as you might suspect from the Latin genus and species, have a bit of folklore under its belt. Cyanus was a youth in Greek legend who worshipped Chloris (or Flora), and spent every waking hour gathering flowers for her altar. (Today we call that a stalker.) When he died, the goddess gave his name to the plant, though some believed she turned him into the plant.
Centaurea comes to us from the Centaur Chiron, who cured a festering wound that was made with an arrow dipped in the Hydra’s blood. The wound was cured by covering it with the flowers of this plant, which now bears his name as its genus name. This also gave the plant its reputation for great healing properties.

Sowing Direct :
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

Cultivation:
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.
