What is Cornflower?

Cornflower is wildflowers that grow annually, usually in cornfields, hence “cornflowers”. These flowers are native to Europe and in the same family as sunflowers and daisies

Although it has become popular in other areas worldwide, such as North America and Canada, it is endangered in its native home due to pesticides, pollution, and other agricultural impacts.

The Cornflower thrives the best in full sunlight and doesn’t do very well in shaded or even partially shaded areas and requires porous, nutrient-rich soil.

When Does Cornflower Bloom

You will notice cornflowers mixed in with warm weather seasonal crops, in agricultural areas. Cornflowers bloom in the summer from June until August. In full-bloom, these plants can get up to 2 ½ feet tall with a diameter of about one foot around. 

They showcase a beautiful dark blue flower on top of a light green stem. Adding a great amount of colour to every field they grow in.

How to Collect Cornflower Seeds

Cornflower seeds will typically ripen in the fall months between August and October. It is always best to collect these seeds early in the season almost as soon as they become ripe. Doing this will ensure you do not wait too long and the seeds dry up and get taken away by the breeze or other outside factors.

To collect cornflower seeds, you will want to pull them directly out of the dried-up flower head. These seeds are very small and can be challenging to handle at times but can easily be stored in jars or even envelopes.

Many people will pick these seeds to re-sow them in different areas in other areas.

How Tall Do Cornflowers Grow?

The size of cornflowers will depend on the location and environment they have to live in. These plants, much like sunflowers, grow very strong stalks or stems, making them ideal for growing tall and holding up heavier flowers and leaves.

The average size of a cornflower plant is around 36-inches but can get a little taller during the summer and will be much shorter in the spring as they are beginning to grow for the season.

Do Cornflowers Come Back Every Year?

Cornflowers are a great investment to make for anyone who is interested in using them for their health and wellness benefits because they are perennials that keep coming back year after year.

Grow Cornflowers For Bees and Wildlife

Cornflowers are great for wildlife and are one of the top supporting bee plants grown in nature, thanks to the pollen and nectar it supplies.

These wildflowers are also beneficial to birds once their seeds have ripened and start to loosen up, creating a delicious food source. 

Sadly, the already at-risk bee population is struggling to find many Cornflowers to thrive off of because these plants are endangered themselves.

Do Cornflowers Have Pollen?

Yes, cornflowers have enough pollen to keep a bee interested, although it isn’t a whole lot. These plants offer about half of a microgram per flower head. 

Bees do require pollen to survive as it is full of nutrients and proteins and is usually used as larva food but also transported from one flower to the next, pollinating throughout nature as it moves along.

Does Cornflower Have Nectar?

Cornflowers are one of the best nectar suppliers offered in the wild and provide bees with plenty of nectar to be consumed for their carbohydrates given them plenty of energy. The bumblebee keeps nectar stored in pods for the queen bee, whereas honeybees utilize this sugary treat to turn into honey.

Cornflowers are actually one of the very few plants that have extrafloral nectaries. These are small areas that offer droplets of nectar that are not the plant itself. This seems to be a great stop-off for honeybees, in particular, seeing that 80% of bees visiting these flowers are honey bees.

Although the tiny drops do not provide nearly the same amount of nectar as the flower itself, it can be a sweet treat rewarded to the bee for a hard day’s work.

When to Sow Cornflower Seeds

The best time to sow cornflower seed is in early spring producing full blooming flowers in the summertime. 

Many people will use the seeds they harvested in the year before to re-grow their new crop or to even pack up and use to increase the wild population through bee bombs and wildflower packs

A bee bomb is a pod of seeds held together in a hunk of clay. When placed into the wild, the seeds will start to loosen, fall into the soil, and germinate, and wild plants grow. These wild plants are like little bee hotels, giving them options to visit one plant to the next.

How to Grow Cornflower

Because Cornflowers are used to thriving in the wild, they are very hardy and durable but do require some simple basic environmental attributes to thrive.

Never plant your seeds until the last frost of the year. If you start too early, it is likely they will not survive. When it is time, dig a row in the soil about 6-inches down loosen up the dirt so air can flow through and moisture can flow out.

Next, place your seed into the soil about one inch down, keeping the seeds about 10-12 inches apart, and pack the soil on top gently, not compacting the soil too tight.

Water your seeds often, and they should start to grow in about 8-10 days.
