How To Plant Cosmos From Seeds
I love having a cut flower garden and this year I am adding Cosmos to my cut garden beds and showing you how to plant Cosmos from seeds.
I have read that they are profuse annual bloomers that are perfect for the cottage garden. They are known as very easy flowers to grow from seed and will last long through the summer until the first frost.
Cut and Come Again Flowers
When I began thinking about what seeds to plant for my cut flower garden this year, I looked for flowers that would continue to bloom all season long. I have planted Zinnias for several years, and I love that I can cut them, and then they will bloom again. Cosmos fall into that same category.
I don’t like to spend a lot of money on annuals because they only last one season, but one of the benefits of growing Cosmos is that you can save the seeds after they are finished blooming. You will then have seeds for the next season.
Planting Cosmos Seeds
I chose to plant a few cosmos seeds in this galvanized wash tub. We pulled the metal stand with the wheels off the property that we are currently cleaning off, and then at a later date, we found the washtub. I was so happy to see that the washtub fit perfectly on the metal frame.
I had been trying to decide what I wanted to plant in front of the Peonies that are just in front of the old white metal bed frame. Peonies only bloom in the Spring, and I needed something for the Summer and Fall. I love how this combination came together.

How to Plant Cosmos From Seeds
Light: Cosmos prefer an area with a lot of sun.
Soil: Prepare an area that is rock free, and has good loose soil. Avoid using fertilizers that contain high amounts of nitrogen, this can cause foliage to develop faster than flower blooms.
Time: Sow seeds directly in the ground once all danger of frost has passed.
Spacing: I scattered my seeds on the soil and lightly covered them with dirt. Once the seeds begin to sprout, I will thin the seedlings out to 10-12 inches apart. This will give them plenty of air circulation and room to grow.
White Cosmos Varieties
The first planting of Cosmos that I planted were a variety called, Afternoon White. In a few weeks, I will do another planting of Cosmos called Purity and Psyche White. This will give me an abundance of cut flowers all in a variety of white shades.
I look forward to having a houseful of blooms all summer long. Do you grow Cosmos? I would love to hear your tips and feel free to share your favorite varieties.

My Grandson (3 yr. old) and I started cosmos seeds indoors and just transplanted them outside. We planted a mixed dwarf variety. So fun, just passing on the love ?to the next generation!
I would love to have these in the

here, as we cannot plant anything
until after Mother’s Day.
We have more Perrenials than
Annuals. My fav little garden

I have been growing cosmos for 15ish yrs. I harvest the seeds off the plants about 5-6 x’s a summer/fall & I reseed those seeds the following yr. I have found them to be hardy seeds/plants in that, if watered regularly and then periodically after they bloom they will grow in any soil. I also started throwing them in bare rocks, watering regularly until I see them sprout. They grow beautifully.
I have compliments every yr as they bloom all summer until the 1st frost.
As some annual plants that may reseed themselves, I have not let the seeds drop from the Cosmo plants to see if they will reseed until this last fall, I am anxious to see if some will come back.
Hello! I loved your video and post on Cosmos. I’m going to sow seeds for the first time (ever!). When you say that when the seedlings sprout, you will thin them to 10-12″ apart, how do you do that/what does that mean? Thank you!!
