Learn to plant popcorn grass (AKA popcorn gress in Norway)! Did you know that you can eat the tender shoots that sprout from popcorn seeds? It’s true! Keep reading for a simple how-to that will answer all of your questions on how to grow popcorn sprouts. These are very likely the sweetest greens you’ve ever tasted. Sprouting popcorn kernels is probably easier than you’d think!
I threw a couple popcorn kernels in with my basil plant and a week later I have 3 little sprouts.

Not to brag, but I think today’s recipe how-to is so darn cool. If you haven’t tried growing your own popcorn greens yet, now might be a great time.
I purchase microgreen seeds through Johnny’s Selected Seeds. The last time I was perusing their products, I noticed that they sell popcorn shoot seeds.
🌱 What are popcorn shoots?
Popcorn shoots are simply the edible sprouts of popcorn kernels! The process for growing these greens is quite easy.
I let my first crop grow in the sun for a total of two weeks. The green leaves were a little fibrous, but the biggest surprise was how incredibly sweet they were.
I’ve heard some say that young popcorn shoots taste a bit like biting into a fresh ear of corn. We think the shoots are so sweet they taste a lot like stevia. It is pretty amazing.
I’ve also read that popcorn shoots grown in the dark for only one week make the best eating. They are sweet but not fibrous like the older green leaves. I currently have a batch growing in my closet, and I look forward to seeing how it goes! (Update: we did like one-week shoots better.)
The downside of shoots grown in the dark is that they remain yellow. You don’t get the lush verdant look of shoots grown in the sun.
🍿 Popcorn Grass Supplies
The items that you need to grow popcorn greens are things you may already have on hand. Here’s what you need:
- Popcorn
- A canning jar or other vessel for soaking the seeds
- Potting soil
- An 8”x8” metal pan with clear lid (I used one of those disposable baking pans; a slightly larger-sized pan is fine too)
- Water
That’s it! You don’t even need to order from a garden center to get the popcorn. Using plain popcorn kernels from the grocery store should work.
I used Bob’s Red Mill white popcorn kernels because that is what my store happened to have. However, any white or yellow popcorn kernels should sprout as long as they are not too old. Popcorn that has been sitting on the shelf for years may not sprout for you.
If you buy from stores that have a high product turnover, just about any plain popcorn you can get your hands on should work. Dry goods tend not to remain unbought on store shelves for long these days.
Even if you don’t like how sweet the greens are, this is a fun project to do with kids. Why not try it? No matter what sort of climate you live in, you can have fresh greens without a trip to the store.
I’ve been really into slow food and DIY lately, including gardening. Luckily, it’s possible to grow things in any climate, even with limited garden-related knowledge and supplies!
🌽 How to Grow Popcorn Grass
Here are the step-by-step instructions for growing popcorn grass:
Put ½ cup popcorn kernels in a glass jar and fill with warm water. Cover the jar with cheesecloth to prevent dust from getting in while still allowing air.
Let the popcorn kernels soak for three days at room temperature. Drain and refill the jar after 1½ days to keep the water fresh.
After three days, drain the water from the jar. Fill an 8-inch by 8-inch (20×20 cm) metal baking pan with 1-1½ inches (2.54-3.81 cm) of potting soil. Spread the popcorn seeds out in a single layer on the soil. Press the seeds into the soil but do not cover them with the soil.
Moisten the soil well with water and cover the baking pan with a clear lid. You want the seeds to stay moist throughout the growing process. If you live in a more humid area and are getting mold, remove the lid from the baking pan.
For tender, yellow shoots, grow the popcorn shoots in a dark place for approximately one week.
For more fibrous green shoots, grow the popcorn next to a sunny window. You can eat them at one week for more tender greens or two weeks for a higher yield of tougher greens. Here is what one week of growth looks like…
If you grow them for two weeks, you may need to remove the lid for the last few days, as your greens will be crowding the container. Here is what you’ll see after two weeks of growth…
When you are ready to harvest, cut them with sharp scissors above the soil line. Remove any seed coats that are sticking to the greens. Your shoots will be around 3-6 inches (7.6-15.2 cm) long.
➕ What are popcorn shoots used for?
You can use popcorn shoots just as you would other microgreens. Use popcorn microgreens to top salads, sprinkle them in sandwiches, or saute them for a veggie side dish. Here are a few ways to use popcorn grass:

Ingredients
- ½ cup popcorn kernels (unpopped, unseasoned)

- Let the popcorn kernels soak for three days at room temperature. You should drain and refill the jar after 1½ days to keep the water fresh.
- After three days, drain the water from the jar. Fill an 8-inch by 8-inch (20×20 cm) metal baking pan with 1-1½ inches (2.54-3.81 cm) of potting soil. Spread the popcorn seeds out in a single layer on the soil. Press the seeds into the soil but do not cover them with the soil.

Notes
💭 Expert Tips from Dietitian Summer Yule
This is a level 1 recipe (may help support fat loss). Are popcorn sprouts good for you? Leafy greens are about as close as you can get if you are looking for zero-calorie whole food options. While they don’t actually contain zero calories, I think it’s fine to consider them “free foods” on almost any weight loss program. If you are a volume eater as I am, aim to get some leafy greens into your diet daily. They will aid in providing more fiber to your meals to help you feel full. Additionally, they fit nicely into almost all eating patterns (such as low-carb, vegetarian, vegan, etc.) and provide nutrients such as vitamin C. Nutrition information is for one serving.

FAQs
Where does popcorn come from?
Popcorn comes from a certain type of corn kernel that has a hard outer shell (source). When you heat the kernel, moisture trapped inside the hard shell turns to steam. Pressure builds in the kernel until the outer shell pops open, giving us a fluffy piece of popcorn.
Is popcorn grass safe for cats?
Popcorn grass shouldn’t be fed to cats, as it can give them an upset stomach. (Please note this is not the same as the popcorn plant, which also shouldn’t be fed to cats.) If you want to give your cats greens, try growing cat grass instead.
I hope you found this post helpful in answering all of your questions on how do you grow popcorn greens. If you grow these, tell me how you think these taste the best:
- After being raised in the dark or the light?
- One week or two weeks?
Also, I’d love to see your popcorn green culinary creations! I’ve been planting popcorn kernels to use in salads or lightly steamed as a veggie side dish. Hit me up with some more ideas!

Thanks for this. I had a bag of popcorn three years past its date and thought to myself, if I’m not going to eat them, why not use some and see if it grows? I did what you said and kept them in my conservatory. To my surprise, a month on, about 30 out of 100 kernels have turned into plants, and more seem to be popping up. I tasted one and thought it was a bit too grassy for me, so instead I have separated them into pots and I’ll see how big they grow. I live in Scotland so the weather might not be hot enough, but it’s an interesting experiment!
Hi Mark, sounds like a neat experiment! If you end up with ears of corn, I’d love to hear about it 🙂
That is so awesome! I had no idea that you could grow popcorn greens. And eat them! Definitely going to try this one! Thanks!!!!!
This was relatively new to me too! I can’t believe I went all of these years without knowing about this!
How do I grow popcorn greens? I don’t, but after seeing your post, I definitely need to undo that deficit. Again, I appreciate the inspiration, Summer. Monkey see, monkey do and all.
More than a little reminiscent of that “special project” we all undertook in second grade, growing peas in a jar. I don’t recall mine turning out so well, but you’ve shown what’s possible with the right knowledge. Again, nice jumpstart, Summer!
Haha, thanks! This is one of the easier things to grow; I think most can have success with it. It’s really amazing how sweet they are. I’d say that was the biggest surprise in all of this!
This is one that I definitely have to try!
I’d love to hear how it turns out!
I threw a couple popcorn kernels in with my basil plant and a week later I have 3 little sprouts.
Love that! 🙂
