For a small investment of time and garden space, you will be able to fill your house with these cheerful flowers all summer long. I would love to hear your experience with this wonderful group of plants. Do you grow cosmos or plan to add them to your garden this coming season? If so, what are your favorite varieties?
Lastly, if you find this information is helpful, I would love it if you would share it with your friends. These are ALL gorgeous. I tried to grow a mix this year, but they turned out… meh. I have some I planted in partial shade too, they probably only got 4 hours of good sunlight and did NOT do well at all, so I know where I failed there.
I already have some Xanthos ready to go, so exciting. I may try them in my greenhouse instead of outside to see if I get better results.
Now I just need some Apricot Lemonade and Daydream in my life! I definetly love Cosmos. If you want I can ship it to you. I grew cosmos four years ago. They were amazing. Can I pinch my cosmos more than once?
Or is it better to do it once, wait for blooms, and harvesting will cause more branching? I find your updates, books and videos so helpful!
Thank you from the bottom of my heart! If netting is preferable or at least acceptable, can you tell me the height at which you place it?
Would cosmos be the same? Also, could corralling work or them? Your beautiful photos of a Cupcake Blush brought me in from Google. I received my cosmo seeds from Floret ant Planted them here in zone 6 about 3 weeks ago Inside my small greenhouse along with other seeds from Floret.
The cosmo and the other variety of seeds popped up before any other seeds I had sown. I also received the cut flower book and Dahlia book which have been a great joy to read and thumb through.
Cosmos was the very first seed that successfully grew! Actually threw out the dinking room furniture and the entire room is dedicated to seedlings.
The potting bench is in the living room! All from one seed that made it planted directly in the garden. Thank you for a feel good article! Hello: Thanks ever so much for your helpful information. I am planning on planting a cutting garden this year trying several new varieties and unsure of how many cosmos to plant. I would like to start the cosmos indoors to get a jump start on the season. I take bouquets of dahlias, gladiolus, delphiniums and sunflowers to church on Sunday and want to make bouquets from some of the earlier blooming flowers.
To me flowers are meant to be shared. If I had another 25 years I would want to be working on your farm. Thank you for all you do and all you share. You make it all look like a dream! Just wondering how you manage slugs? Do you need start to manage immediately when you plant seeds or seedlings and what products do you apply? I have tonnes of slugs and need to start taking them seriously as I would like my plants to make a full expression.
Just discovered you guys. How inspiring! I am planning a cutting garden, purely for pleasure, and you have given me so many ideas. These are the most amazing flowers and I am still in october having my cosmos buds come into bloom. I am not sure how to cut back for the winter so any help would be appreciated. Thanks so much! Any ideas on what i may have done wrong? Literally about 4 feet tall and not one bloom in sight. So sad:. Does anyone have any advice for cosmos that will not bloom?
I have a bunch of plants growing beautifully from fresh Floret seeds but not one single bud has appeared. My favorite varieties are Purity, Double Click, and Seashell. I hope someone finds this information helpful. No, these are true annuals. I keep them blooming until Oct or Nov in my zone 9 garden by constantly cutting the flowers but eventually they give up and die back. For comparison I can get two or three years out of my petunias. Hi there, we have a small growing space, where we grow predominately annuals for selling as cut flowers.
We have planted are first lot of cosmos. Once the sweet peas are over , I was thinking of preparing the bed for cosmos, will that be too late in the season though? I think our sweet peas have another two weeks to go. This year I am in a little different set-up and will not be able to start the plants inside. I will need to do a direct planting into the ground. These are for my personal yard, so there will be a few beds, but not outstanding amounts. I live in Utah and we have a lot of slugs, potato bugs, and grasshoppers.
I am concerned about the sprouts getting eaten up before they can grow. Do you have any natural — diy suggestions on how to prevent insects from eating the sprouts? Hello Floret Team! I absolutely love cosmos and how airy and light they are. However, the few times I have tried to grow them I grow only beautiful green foliage! I have fertile soil as I have been amending with compost and mushroom manure through the years so I can grow roses and other fertile soil loving plants.
I am assuming this must be the reason and I am wondering what you can suggest adding to my soil to grow cosmos flowers?
Thanks very much and I love your website and I look forward to all the email posts. Cosmos grow beautifully in full sun in large pots for the deck. I do it all the time. Such a lovely flower. My fondest memory of cosmos was combining them with my first plantings of new asparagus.
There is nothing more lovely than seeing a wonderful row of cosmos flowers and feathery fronds of asparagus greenery dancing in a summer breeze, giving hope you can be patient for a taste someday of the forbidden fruit, and pluck posies without guilt!
I purchased the book for myself and also my lovely daughter in law, Kate. Looking forward to seeing you on Magnolia channel in the fall. Cosmos did just fine for me in a big pot last summer. Also planted out in the community garden. In our unfenced garden we have lots of deer, and they never touched the cosmos. They bloomed gloriously through the summer. How much sunlight do cosmos need? Hi Jane, They need at least hours of direct sunlight to flower properly.
As a kid in Nova Scotia more than a few years back, I grew Cosmos in our back garden. After seeding direct into the garden, I watched as the young plants started to grow. As they began to flower, I chose one plant and picked off ALL the buds. That plat did not bloom all summer but it developed into a massive plant about 4 feet high with a stalk well over an inc in diameter.
As the rest of the Cosmos reaced the end of their productive life, I let this giant finally bloom, and bloom it did.
Surviving a number of frosts on its own, it showed off it colours well into December after all its garden mates were just a memory. If you decide to try this, pick several of your plants to "debud" among the rest of your plants. You should end up with a long lastinf show of colour from these pretty and delicate looking beauties. Good Luck! It's only a handful amount on the soil but I noticed beforehand small white powdery on leaves of cosmos.
Can I use Neem oil for this? I'm thinking it's a matter of powdery mildew fungus problem? Thanks by the way on responding on my previous inquiry. I have orange cosmos here and they just grew in my front yard. They're beautiful. What stage of a spent bloom are the seeds in? When the heads and stems are still green and the petals have fallen?
Or do I wait for the stems to turn brown and the heads are dry and I see spikes? They're not even shaped like "balls"; they look almost dead. The botanical name for the orange variety is Cosmos sulphureus. Most cosmos varieties develop seedheads if you leave the faded flowers on the plants. The seeds are in the center of the flower.
As the flower dries they start to separate and you can see them quite clearly about an eighth of an inch long. Let them dry right on the flower but make sure you get them as they start to open up and separate. Put the flowers into a paper bag and shake out the seeds.

It was at least another 50 years until cosmos got to the United States, indirectly from England and Spain and more directly from Mexico.
