We’ve all heard how incredible leafy green vegetables are for your health: high in vitamins, minerals and fiber and yet low in calories. They’re usually considered an unlimited food choice regardless of diet, so it’s useful to learn how to incorporate various options into your eating habits.

If you’re on such a mission, there’s a good chance you’ll run into both collard greens and mustard greens as you explore your options. 

So what is the difference between mustard and collard greens? The main difference is that mustard greens are considered an herb while collard greens are part of the cabbage family. Their flavors are also vastly different, and they each contain various levels of vitamins and minerals.

Having leaves, plenty of nutrition and being the color green are about the only similarities these two plants share, so before you chow down, it’s a good idea to learn a bit more about the differences between collard greens and mustard greens – primarily, they’re respective flavor profiles. This article will answer all your questions and probably a few you didn’t even think to ask.

What Are Collard Greens

Collard greens are large, thick leafy greens in the brassica family, along with cabbage, kale, and Swiss chard. The name collard comes from the less appetizing Greek word, “colewort,” which simply means wild cabbage.

They can grow up to 2 feet tall, but they get tougher the larger they are. Collard greens are commonly available in most supermarkets year-round, and when you’re shopping for them you want to find a bunch that is a deep, rich green without any dried edges or holes.

Almost all conventionally grown greens are sprayed frequently with insecticides, so if you can find them organic, it’s a good time to invest in this upgrade.

If not, be sure to wash the leaves well, using a solution of vinegar water if possible. The leaves are dense and will stand up to a good wash, unlike their cousin spinach that wilts just looking at water.

What Are Mustard Greens

Mustard greens are actually considered an herb, even though they’re a member of the brassica family of vegetables, along with collard greens. They have a very powerful flavor, which is a good indicator that they also have a very powerful nutritional profile. 

Mustard greens begin as the seeds that we know best for their potential to create one of the world’s favorite condiments: mustard. At every stage of growth, mustard greens are edible, tasty and extremely healthy. 

Many people also enjoy sprouting their seeds and eating them much like any other type of sprouts, such as alfalfa or broccoli sprouts. The longer the seeds grow, the larger the leaves will become.

They’re quite easy to grow for yourself, but depending on where you live, there’s a good chance you can find either sprouts or greens at your local grocery store or possibly specialty health food store.
