How To Collect Seeds-Green Onions!


I love green onions! I toss them in almost everything; soups, salads, and even in my sandwiches. I love them fresh, and sautΓ©ed in any oil or butter, and grilled!

You’ve seen how I propagate them in my window sill here…but I also grow them in my garden. I collect the seeds so that I can do it all over again…why? Because I love green onions!


You can re-grow green onions this way…Cut off most of the green tops and plant the white part and roots (of course) in good soil. In a few days you will see it start to grow. What “green” you see here is about 2-3 days of growth. They grow fast. They love a sunny window sill and gentle watering.

If you’ve ever grown green onions and let them bolt, then you already know the flowers are so pretty! Another plus is the bees like them too! So I always let a good amount of my green onions bloom to show some love to the bees! They work so hard and this is the least I can do for them!


Flowers + Bees—Bees + Flowers! The wonders in nature never cease to amaze me. I am humbled each time I step outside to see the beauty of it all.


Mint in the background. I love to brush my hand along the mint. Such a refreshing fragrance! Inhale deeply and smile. Give it a try!


Half of this garden bed I’ve allowed to “bolt” (a fancy way of saying letting the plant “flower” so you can harvest the seeds off it). After the green onion flowers, I leave the flowers on the plant to dry. It is in each little blossom where the onion seeds are found. How cool is mother nature?!


After the blossoms dry, I will either store the “whole” head or take them apart like you see here. Just make sure the blossoms are totally dry so you don’t get any mold growth.

You can “re-grow” green onions by putting the bottom parts in water or soil and if you grow them outdoors, you can allow a few to bloom flowers and then collect their seeds and then plant the seeds! Amazing right?! And simple as well! I love that.

I harvest the green onion by snipping them with scissors. Even the plants that are bolting; I will snip the long green stems (NOT the stems with flowers on them). If I let the plant grow too much and the greens are thicker, I make a soup with the greens, much like you would do with leeks. I’ve also grilled them. Rarely anything goes to waste in the garden and really if I don’t eat everything, it all gets composted back in!

Did you know?

Green onions are full of vitamin K and C.

Green onions are good for your eyes. With vitamin A and carotenoids (cancer fighting properties) and both Zeaxanthin and Lutein, working together to keep the eyes healthy!

One last picture…..


A nice surprise: If you already follow me on instagram, you’ve already seen this little guy! (Eastern milk snake). I found him on one of my walks along a trail I mowed on the back half of my property. What a cutie right?

Green onions are one of the easiest plants to grow. I hope you give this plant a try. If you’ve thought you didn’t have a “green thumb”, this plant will give you hope! Collect the seeds and you will never have to buy them again!

Like it, share it! With love and peace, Koko πŸ™‚

  1. I’ll have to try this!!! I currently don’t grow green onions, just yellow ones. Do you think I could do this with ones bought from the grocery store? Lovely post!

    • Hahahaha! That little guy was so tiny I could fit him in my pocket! Seriously thinner than my pinky! I have yet to see a snake in my garden, bough no shortage of bunnies and deer! Lovely to have you stop by. Be well my friend! πŸ™‚

  2. Wow, didn’t know about replanting the tops. I might retry this. If only it would rain so they had some damp soil to go into.

    Good on you, anyway, for saving seed. The onion flowers are gorgeous.

  3. I’ve been thinking of trying growing some in soil. I’ve done it in water before. I love green onions and it would be nice to have a supply at the ready. They are so tasty!

    I changed my name on here to this from DuckyLayne. I don’t know if you saw that update blog post on that or not. Glad to see a new post from you. Blessed Be!!!!

    • I love garlic too! They are in the same bed as my green onion! Do try this. It really is great to have them on hand. Fresh is so delicious! Hope you have a lovely day! πŸ™‚

  4. About 3 weeks ago I finally had the chance to try and grow onions from my window sill with the help of your YouTube video. It’s amazing how fast they grow! It’s such a fun process to see them grow. I can’t wait to harvest my first batch πŸ™‚

    • This makes me so happy! I am thrilled you did it! Isn’t is awesome to have fresh green onion on hand? And better yet, you grew it yourself! How wonderful for you! Keep on growing! Have a happy Friday! πŸ™‚

  5. A woman of so many talents, with so much knowledge, AND…who regularly thinks outside the box!

    I am always waiting for your next post, in order to see what’s the next cool idea you have up your sleeve. So many great ideas, you must obviously have some long sleeves.

    I very much look forward to reading your blog, as I learn something every single time.

    Thank you so much for the great info!

    Have a wonderful day!

    • I always enjoy your comments. They keep me believing I can do it! My sleeves are long, though some days it feels like i’ve got on a tank-top! Hope all is well with you! Thank you so much for the wonderful comment. Peace to you! Koko:)

  6. I’ve allotted a few of my green onions to have the simple pleasure of bolting, but they are not cooperating yet, still growing nice and tall.. I must stop snipping off the tops to use in my stir fry or else I will not have any that will bolt for me.. The radishes from Spring have all bolted and I’m in the beginning stages of collecting those seeds.. I love free seeds from good old mother nature.. your green onion flower heads look amazing.. Take care, Laura

    • Free seeds are the wonderful gifts that Mother Nature gives us and I thank her for that! I tell ya, I am so thankful for this blogging world and to get the opportunity to meet people I wouldn’t have met otherwise. You could have been my sister! We do many of the same things. Lovely to have you here Laura. Take care of yourself! Hugs, Koko:)

      • Koko I feel the same way as I’ve just said in the previous message to you.. It’s a pure miracle some of us just connect so smoothly..

        Take care my dear..


      • Happy Sunday Laura! I pick my baby girl up from the airport tomorrow! I’m excited. The sun is out today. Yesterday not so much. I’m going out to pick tomatoes and squash! Yum! Hope your day is splendid! πŸ™‚

      • Happy Sunday evening back to you my dear.. Today, has been full of ups and downs, but I kept very busy this morning in the garden, then made ice cream, and one to making or trying to make another loaf of gluten free bread for my sons eczema condition.. I’m struggling with making this new way of baking without flour… wheat that is.. if you have any tricks about gluten free bread making jot it down here for me.. Then I made Italian pork meat balls and added wonderful spicy extras to the crock pot.. Was a delightful dinner and very little clean up.. Sleep well my dear and I can almost see you smiling over seeing your daughter very soon.. hugs from Laura

      • Dinner sounds lovely. Mine was chomping down a few cucumbers I had harvested from the garden and a few tomatoes that never made it inside! Good thing it rained yesterday! Cleaned them for me! I haven’t baked much gluten free bread. If I find a good recipe, I will pass it on to you. Can you see the smiles? My daughter is so sweet. She calls and texts me daily with what she is doing. She is sun burnt from watching the surf competition and of course she called to ask what to do about the burn! Hahaha. Kids! You sleep well too! πŸ™‚

      • Yes the smiley faces shows up here.. and that’s just proof for you that your daughter respects your wisdom and readily accepts your knowledge.. It’s a blessing ~ Proud of you my dear as a loving mother.. Keep up the good work.. hugs from Laura

  7. Hi Koko, I love the tips here! I’m also a big fan of green onions. I put them in a lot of things too, with my favourites being salad and miso soup :). I have some growing in my garden as well but they don’t look quite as lush as yours. Maybe it needs more sun? Or better soil?

    • The bed that my green onions are in could use better soil. I don’t think they are too picky. I will amend the soil soon by adding another bag of good top soil. They do like sun, so that might be the thing. But add some more good soil and put them in the sun. Glad to know another green onion fan! Cheers to you Amy! Have a wonderful day! πŸ™‚

    • Isn’t he a beauty?! I was so excited to have come across him! Along my walks, I’ve seen a couple different ones. I so love nature! Seeing green things growing is so refreshing. I can’t help but grow things! Glad you have something green in your window sill. Have a happy day Liam. Hugs! Koko:)

  8. I love green onions too and look forward to picking some soon in my dad’s garden πŸ™‚ Since I do not have a garden of my own now, I may need to try the window sill or terrace pot method. That snake has beautiful colors!

    • I’m thrilled for you for your visit to see your dad! Yes grow some on your terrace or window sill. πŸ™‚ He was a beauty! I love coming across the many wonders of nature. I don’t get to see as many as you though! Much happiness to you as you visit your family. And of course take lots of pictures! Hahaha. Enjoy yourself Helen! πŸ™‚

  9. I love green onions also, but never have tried to grow them! Thank you Koko for following my blog. I will certainly take time to visit yours as well. I hope your day is a happy one! πŸ™‚

    • My day has been happy! I try daily to make improvements. I certainly hope you find interesting posts at atkokosplace to keep you coming back! I wish you well. Enjoy the rest of your weekend! Koko:)

  10. Hi, hope you have a wonderful day and week. I have a pot which could handle growing some onions in my apt. Thanks for the tip. I like the pretty garden snake and often look at critters! I think your blog holds some wonders to check out soon. . . Hugs, Robin

    • Nice to see you here Robin! Your kind words made my day! Growing green onions in a pot will be perfect. It really is fun to do and nice to have them fresh on hand! I hope to see you here again. Thank you again for your kind comment. I hope you have a wonderful weekend! Hugs back! Koko:)

  12. I love green onions as well and the flowers are very pretty:) I love your appreciation of nature! I don’t know if I would call bees and snakes “cute” LOL (I would take off running the other direction), but I do have tons of respect for all beautiful creatures:)

    • Hahaha…snakes are cute when they are babies…and bees, well I love them, I really do! They are so helpful in so many ways and their fuzzy bodies get me every time! Teehee! πŸ™‚ I never knew how pretty onion flowers could be until I grew them. I’ve seen the blossom colors from white to pinks to purples….so very pretty indeed! Hope you are doing well Nena! Have a great weekend! πŸ™‚

  13. Lovely tips about how to grow / regrow onions. Love them. That snake is another matter. You are brave. I’ll keep my distance. πŸ™‚
    (ps. Just made chocolate mint ice cream.) Love mint.

    • The snake was just a baby! Teehee…seriously if it were six feet, I’d probably not get so close! I can’t help but think they are so cute when they are tiny. πŸ˜‰ Wonderful to have you stop by! Chocolate mint ice cream…any leftovers?! Hahahaha….Yum! πŸ™‚

    • It is interesting how some foods are more popular in another country. I love all kinds of foods. Awesome to see you here. Thank you so much for all the comments. I totally appreciate that more than you know. Be well, Koko πŸ™‚

      • It is quite weird. I actually don’t like loads of products. It’s such a shame as I could make much more interesting dishes if I would! Haha and no problem at all, same goes to you 😘

  14. I love this article as I love onions. I didn’t know how to harvest their seeds. Very interesting. In the future, when I’m trying to remember white on black and red on yellow or red on black -oh well, I will remember your words and the picture of this wonderful snake and know I don’t have to fear black on white/white on black However!

    • I’m happy to know you got something out of the post! The little snake was indeed a cute fella. He was just a baby. Now if I had come across him and he was like say, “six feet”, I might be a little nervous. Then again, not poisonous. If my son was with me, he would have picked him up! Onions are wonderful. So healthy too. I love that they are so easy to grow. When it’s snowing out, I am glad to know I can grow them indoors! Take care and thank you kindly for your comment. Koko πŸ™‚

    • Wild garlic is so good! Onions and garlic; so good for us too! Nice to see you Nancy! Hope all is well with you! Enjoy your weekend. I’m hoping for less humidity, but I will take whatever is coming and make good use of the sunshine we are supposed to have! Take care, Koko πŸ™‚

    • I have done this with green onions and big purple onions! So, I believe you can. If you are new to this, try it with green onions first. They also take up less space. I hope you give it a try. It sure is fun to try new things! Take care and happy gardening! πŸ™‚

    • And with how easy they are to cultivate….! Too bad I can’t just crunch on them while working in the garden like I do with tomatoes! Well I could, but no one would want to be near me. Teehee! πŸ˜‰ Enjoy the rest of your week!

      • Haha that’s true! 😳 This gave me a huge insight and I’ll have to incorporate it in my diet a lot more. Thanks again and you have an amazing week too hun ☺️ xx

  15. I love adding green onions in my cooking. I’m going to try to grow onions next year, but in a pot. I dislike snake very much. I don’t think I want to see one he he…Thanks for sharing your expertise, Koko. Best wishes. ❀

  16. Beautiful photos Koko and good information πŸ™‚
    I forgot to collect the seeds this year, oops. Fortunately, as you described, they are easy to re-grow…

    • I have several plants/flowers with seeds in it that I still need to extract. All drying/hanging in various places in my home. I’ve been meaning to get to them, but life…ahhhh life just keeps moving. So I must move with it and some things are left to sit until I can get to it again. I’m hoping my geranium seeds will bring many flowers next year! Until then, the geraniums, oregano, sage, and various others will have to wait. I’ve had my hands full with paint and nails and projects oh my! I will make the time to visit your page. Take care of yourself Patty. Enjoy your evening. πŸ™‚

      • Hi Koki,
        Yes, go with the flow is the key πŸ˜‰
        Over here it’s winter time, I’ll wait until January/February to start sowing again.
        Gives me time to attend to other fun stuff πŸ™‚
        Thanks for the visit and responses! Big hug, XxX

    • Yay! Me too! There are a few sprigs here and there of mint in my garden. They are so hardy even in very cold winter! I can’t wait for the mint to go crazy with growth. I too love the smell. I brush my arms along the leaves when I walk by! Enjoy your day and thank you so much for popping into my world. πŸ™‚

  17. I absolutely did not know that green onions flowered like that!

    I’ve tried re-growing grocery store ones many many times, but often they’d just rot and die (even when I put them in soil). Do you think the time they spent in the store might have to do with how weak they are?

      • It’s a good way to teach people not to throw out seeds! I love my son’s idea of keeping pumpkin πŸŽƒ and watermelon πŸ‰ seeds to grow more the following season. His kids like setting them out on windowsills to dry before they bag them up. ✨

      • Oh how wonderful. I have yet to be able to grow watermelons successfully. I’ve had a few pop up, but nothing to be proud of! As for pumpkin seeds, we can’t help but bake them and eat them all! πŸ˜‰ Well done to your son for teaching his children how food is grown. You did a good job too Mom! Have a lovely day!
