It was raining in that fine, sideways drizzle that soaks you without you knowing it. I was standing under the market’s awning, looking at a big pile of vegetables. There were white cauliflowers that were very tight, dark green broccoli, and shiny cannonball cabbages stacked up like helmets. A child tugged on his mother’s sleeve and asked, “Why do they all look like cousins?” The seller laughed and asked, “Cousins?” They are more like two people. The mother smiled politely, clearly thinking he was just being nice to get more broccoli.
He wasn’t joking.
I couldn’t stop thinking about that idea after a few stalls. What else on this table isn’t what we think it is?
One plant, three kinds of vegetables that are “different”
We usually don’t think about the brassica aisle when we walk by it. You can roast cauliflower, eat broccoli on “healthy days,” or make coleslaw or the soup you said you would make one day. They are in different boxes, have different recipes, and even seem to be in different parts of our brains.
Botanists will tell you something that sounds like a magic trick: Brassica oleracea is the same species as broccoli, cauliflower, and cabbage. Three different people, but they all have the same plant and DNA. It’s like meeting three identical triplets who have all made different choices about how to live their lives.
If that doesn’t make sense, try this. A strong, wild cabbage plant grows on a windy cliff along the Atlantic. It fights the salt and the cold. People began to grow it again and again, keeping seeds from plants that had the traits they liked best. People in one village liked plants with big leaves. Someone else picked the ones with tight heads. Someone else fell in love with flower stalks that were thick and crunchy.
That one wild ancestor has changed into the patchwork we know today: round cabbages, branching broccoli, and cauliflowers that look like brains. Same place of birth. Just generations of people making choices that are quiet and patient.
The species stayed the same; only the parts we chose to look at changed. The flower buds of the plant that grow on the tops of long stems are called broccoli. Cauliflower is also a bunch of small, pale flower buds that are frozen in time. When the leaves curl up into a tight, dense ball, that’s cabbage.
Selective breeding pushed each trait to its limit. Farmers kept seeds from plants that had a little more leaves, were a little more “florety,” and were a little denser. If you keep doing that, you’ll get “different vegetables,” which are really just different parts of the same organism that have been put in the spotlight. *You’ll never look at your plate the same way again after that.
How this hidden family can change your kitchen
When you cook, knowing that these three are siblings gives you a secret power. You stop worrying about strict recipes and start thinking about how things are built. Are the cabbage leaves tight? If you cut them thin and fry them quickly, they act a lot like firm broccoli stems. What are cauliflower florets? You can use them instead of big pieces of broccoli in almost any recipe.
One simple way to do this is to cook them all at once, as if they were one big vegetable with different textures. Put some rough pieces of cabbage, cauliflower florets, and broccoli tops on a tray and roast them with oil and salt. The edges of the cabbage get burned, the cauliflower gets sweet, and the broccoli gets crunchy. Three textures, one pan, and the same plant.
This is a short part of a Tuesday that lasted too long. You get home tired and the fridge is almost empty. There is a sad half of a cabbage, a small head of broccoli, and a piece of cauliflower left over from Sunday. You thought of three different recipes, but you didn’t make any of them. We’ve all been there when dinner feels like a puzzle that makes us sad.
You chop everything up into small pieces and add them to a frying pan with garlic, leftover rice, and soy sauce. It smells like the kind of food you wish takeout would send you ten minutes later. That is Brassica oleracea saving your weeknight without any drama.
This is where science and real life meet. Because they are the same species, they share a lot of nutrients, like fiber, vitamin C, and plant compounds that protect them and taste a little bitter. The differences in taste have more to do with how thick or thin they are than whether they are “good” or “bad” vegetables.
To be honest, no one really weighs out their broccoli and cauliflower every day to get the right amount. You really just make what you have. You waste less, try new things, and stop worrying about whether tonight should be a “cabbage night” or a “broccoli night” if you think of them as cousins who can be switched out. Three different ways to tell the same tale.
Shopping and cooking like you know how to do it with Brassica
The next time you go to the grocery store or market, try this little experiment. Instead of just grabbing “a head of broccoli,” stop and think about what part of this plant you want to work on tonight. A thick heart, leaves, or buds? That one question makes you move your hand differently at the shelf.
If you want something crunchy in your salad, cabbage is a good choice. If you want florets that are soft, bouncy, and can hold sauce, go with broccoli. If you want something meaty and roastable, cauliflower is a good choice. **You are not buying three random vegetables; you are choosing the mood of one very flexible plant.**
We often hold on to food biases we learned as kids. Someone says, “I hate cabbage,” and their face twists as they remember how bad school lunches were. Or “broccoli is boring” because they only know how to cook it until it’s mushy. Under those labels is the same kind of animal, waiting for a second chance.
You don’t feel bad about that. Things get their flavor from more than just buds and leaves. It’s easy to change just one thing: instead of boiling, roast; instead of microwaving, stir-fry; or instead of cooking at all, shred raw. A few small changes can make the same plant taste very different when you eat it.
A farmer I met in Normandy, whose arms were green from picking, said it this way:
He laughed and said, “People think we grow a lot of vegetables, but half of this field is just the same plant in different jackets.”
His words stick with you when you cook.
You can save this quick pocket guide as a screenshot or in your head:
- Cabbage is best for slaws, long braises, stuffed leaves, and crunchy stir-fries.
- Broccoli is great for quick stir-fries, pasta, creamy gratins, and grilling until it gets charred.
- The best ways to use cauliflower are to roast steaks, turn them into “rice,” and make smooth soups.
- For cleaning out the fridge, sheet-pan dinners, curries, and casseroles, a mix of all three is best.
- You can usually use a different one and just change the cooking time a little if the recipe calls for one.
A different way to look at what’s on your plate
Once you know that cauliflower, broccoli, and cabbage are all different types of the same plant, the vegetable aisle looks less like a catalog and more like a family photo. You start to notice things that are the same, like how the veins in the leaves are the same and how the stems branch out in the same way. That little bit of information sticks with you and changes how you think about trash, cook, and shop.
You could try more things, like putting different kinds of vegetables in the same dish or cooking a vegetable you don’t like in a new way. Or maybe you’ll just enjoy the strange pleasure of knowing something that someone else doesn’t, like when they complain about being sick of broccoli while happily eating roasted cauliflower. It doesn’t matter how much you know; it can still be useful. It can help you relax in the kitchen, be more curious, and appreciate the quiet genius of a tough coastal plant that let us turn its body into three everyday classics.

FAQs
Is it true that broccoli, cauliflower, and cabbage are all the same plant?Yes. Brassica oleracea is the plant that all of these are grown from. They have been bred over hundreds of years to bring out different parts of the plant.
Are they both good for you?They all have a lot of fiber, vitamin C, and plant compounds that protect you, but the amounts vary by type and how you cook them.
Can you use one instead of the other in recipes?Yes, a lot of the time. You may need to change the cooking time and the size of the cut, but you can use another brassica in most recipes that call for one.
Why do they taste and look so different if they are the same type?Selective breeding changed the shapes and flavors of plants by making their leaves tighter for cabbage and flower buds bigger for broccoli and cauliflower.
Is this also true for other kinds of vegetables?Yes. For example, carrots come in orange, purple, and white colors, and there are many kinds of kale and Brussels sprouts that are also forms of Brassica oleracea.
