What are Cornflowers?
Cornflowers ( Centaurea cyanus) belong to the plant family ‘Asteraceae’ which includes many other popular plants such as daisies, sunflowers, lettuce, dandelions, and thistles. Are known by many names including the following:
Growing Cornflowers
Initially, the cornflower was a common weed native to Europe, where it grew in abundance in the grain fields. This is how the plant got its name ‘cornflowers’. However, over the years, these plants have become extremely popular. Today, cornflowers are endangered due to the use of herbicides that killed of millions of these plants.
When and Where to Plant Cornflowers
The easiest way to cultivate cornflowers is by sowing their seeds. If you sow the seeds in early spring, your cornflower plants will start blooming by the summer season. On the other hand, sowing them in the early fall can give you plants that will flower in the spring and continue to bloom throughout the summer.
Preparing the Beds
First, make sure that the chosen spot is completely weed-free. Weeds can compete with your cornflower seeds even before they begin to sprout and steal all the nutrition in the soil, leaving nothing for them.
Soil Requirements
Cornflowers can survive in a wide range of soil types including sandy, clayish, chalk-like, and loamy soils. However, they thrive best in well-draining and moist soil.
Sunlight and Temperature
Cornflowers love growing in the full sun but can also tolerate a bit of partial shade. Similarly, despite the fact that they prefer a temperature level of 15-26 Celsius (59-79 Fahrenheit) in atmosphere and around 12 Celsius (57 Fahrenheit) in the soil, they also handle cold climates really well.
Watering
Cornflower plants need to be kept in a moist environment until they’re well-established and stable. Although they have draught-tolerant qualities, watering them frequently will guarantee healthier plants and bigger blooms.
