Cornflower
The blue that gives a meadow its depth, and its name.

Depth in blue
Cornflower is the annual that gives a young meadow its ceiling. Scarlet poppies down low, cornflower up at the shoulder — the two together read as a meadow before anything else has even flowered.
Specs
type annual, native height 40–90 cm flower june – august soil light, low-nutrient seed 1.5 g / m² in a mix
Why we sow it
Like the poppy it's a first-season coloniser, but it lingers a little longer into autumn. On thin, chalky soils it can hold the whole colour of the mix by itself.
