Each fall our garden is filled with colour, from dahlias to heathers and sedums. In August I was checking out which seeds I could plant in the kitchen garden. I had harvested the onions and had a bed waiting to be used. I noticed that not only could I plant fall vegetables but it was time to plant Cosmos for fall blooms. Cosmos are one of the easiest plants to grow from seed and especially useful for new gardeners. Cosmos bipinnatus is a lovely annual suited for a cottage garden style.
Lets take a look at when and how to plant cosmos. Cosmos can be direct sown in the spring when the soil has warmed and then again in August. Just as the first crop is fading you will have new seedlings coming along to fill in the gaps.
It didn’t take me long to find some Cosmos seeds at the local garden shop. Most gardeners are familiar with this annual flower with its single petalled flowers in shades of pink, yellow and white. Not to sound uppity but why not grow a Cosmos with a bit more style? Check out the Cosmos ‘Double Click’ above with its pretty dark pink flowers. I found a seed package of mixed colours of the ‘Double Click’ Cosmos at my local seed shop.
Here is the ‘Double Click’ Cosmos in a lighter shade of pink. The plants grow to about 3′ high but require little support. If you find your plants need some support, use some twigs or bamboo supports to prop them up. I planted them in rows in a raised bed and they are still producing beautiful blooms.
My favourite of the ‘Double Click’ mix has to be the white one with its extra double flowers in a pure white. I will have to grow these in the spring for bouquets. Its stunning!
Each flower is a bit different with this one having a small collarette of petals in the center. Its got more of carefree look compared to the white flower.
Cosmos like a well-drained soil and at least six hours of sun. This is Cosmos ‘Rose Bon Bon’ which I grew for the summer garden. It was started by winter sowing the seeds in milk jugs back in February. What I love about Cosmos is they are drought tolerant. If left to go to seed, you may be lucky enough to have them return next season. I always collect seeds from my Cosmos and this one is no exception. How could I not plant them again next year?
