Blooming Habits:

Fruiting Habits:

Sow in late summer or fall in Phoenix or other mild winter areas. The seeds germinate better if they have been kept in your refrigerator for 5 days before sowing. They do better if sowed in place, in any case they should be covered with a thin layer of soil (0.1 inch - 3 mm), since light tends to inhibit the germination. The seeds take about one and a half weeks to germinate. Thin out to 8 to 12 inches apart (20 to 30 cm). Cornflowers will generally self-sow and come back from year to year.
