How Local Canola Crops are Grown

We were driving down the highway and saw this beautiful view.DSC_0631 We pulled off the road and Googled “What are the yellow flowers growing in the fields?” Wikipedia knew exactly what we were talking about; its first response was, It’s a field of rapeseed (Brassica napus — in the same plant family as mustard, cabbage, and kale). The seeds produced by these plants are crushed to make rapeseed oil.

We had seen this yellow field and barn the week before on the road between Hopkinsville and Cadiz, KY and had pulled over to photograph it.


We had no idea how yellow it was to become. Here it is a week later.


Spectacular as this barn on the side of the highway was, we saw more and bigger yellow fields on the horizon and got back into the car to explore them.


We saw a road with geese strutting across it.


I egged my husband on, “Go down the road. We have four wheel drive. Don’t we?”

He’s curious, too. That’s why I married him. I knew he’d take the road. We drove a little further and what we saw was unbelievable.


In our entire lives, we’d never seen a yellow as yellow as this yellow. We both jumped out of the car to marvel at the fields and then he did something I would never think to do because I am wise and I always consider the snakes, creepy crawlers, and axe-murderers of the world — he waded into the sea of yellow just to see how tall the plants were.


He was kidding, but still.


I told him to move out of the way. A sprayer was coming.


By now I’ve taken a hundred pictures, but the color and light are tantalizing, and I want more. I can’t help myself; I want to capture it all. So I say, “Just a few more pictures and I’ll be done. I promise.” This field was a photographer’s playground; I could have shot in it all day.

I read a more about rapeseed. I learned that in the 1970s, a group of Canadian plant breeders sought to develop an edible, nutritious oil that would grow well in the prairies. They succeeded — the seeds they developed from the rapeseed plant are 44% oil, more than double the oil content of soybeans, and only 7% saturated fat, the lowest of any vegetable oil. The other 56% of the seed is milled to make a high-protein meal used to feed livestock.

The Canadians needed a new, more respectable name for their cultivar. They came up with can-o-l-a, Canada-oil-low-acid. Canola is the most profitable crop grown in Canada, and Canada remains the global center for research on their “Made in Canada” crop.

I saw this sign on the side of the road of a canola fields in Cadiz.


This looks like the flowering heads of kale and broccoli growing in my garden.


I like to see how plants grow and seeds form, so I uprooted a few plants from the side of the road (roadsideya, as I call it) and planted them in my garden.

A follow-up:

This is a photo of canola seed pods taken on June 12. The seeds start to grow inside the pods once the flowers are pollinated and the blooms drop.

Here are the canola seeds from inside the seed pods I grew in my back yard.


This photo from the Internet shows a combine harvesting desiccated canola. Crop desiccation means to apply an herbicide shortly before harvest to aid in uniform crop dry down. Herbicides reduce the green material on a plant so it won’t clog up the combine when it comes time to harvest the seeds and grains.


All of the photos used for this post are untouched (no color enhancements added) except for cropping. In other words, Isn’t the yellow awesome?!

  1. LOVE your descriptions! First time I saw rapeseed growing (made intocanola oil, I believe) was in Ireland. Imagine that yellow beside all the shades of green!

  2. Absolutely lovely! What an awesome drive & day for the both of you! Thanks for sharing all these wonderful pictures, doing the research & then sharing that information with all of us! Always teaching me something new!😄

  3. We drove to Bowling Green, KY last weekend and saw the same beautiful yellow on the sides of the interstate. I have seen it before, but for some reason, it really caught my eye this year. I told the kids we’d have to research and find out what was growing there. Thanks for doing the research for us! 🙂

  4. Funny to see this on your blog. I am actually preparing a post on rapeseed in Wales, where I live. One thing I’ve liked about this oil is that I can imagine it’s quite close to Mustard Oil and use it when cooking Indian food…

  5. Your descriptions made me laugh. You sound like me! I love flowers, intense color, and appreciating the natural glory of it all. But unlike me, you are so good at putting it into words. Thank you!

  6. Bill McDonald July 8th 2019 – We just returned from Whitefish Montana and saw the beautiful fields of yellow – Next to the green of the field next to the yellow was just wonderful – My wife and I took many pictures – We first were told it was a mustard seed field but found out differently later – Living in Kansas I always pointed out the crops and what they were to my children as we traveled across Kansas to Colorado – Great memories
