How to Plant, Grow, and Care for Cosmos Flowers
Beware of Cosmos, a beautiful orange flower, named “Diablo” the dried seed heads will attack, at least according to my wife who gets attacked by everything in the garden. The seeds are about 1/2” long and very sharp when dry, no fun in your shoes or sandals.
I planted 2 Cosmos plants I bought at HD. Something… decided to make my Cosmos plants their evening meal overnight, named down to the nubs? Animal or insect? That critter or critters totally destroyed my delicate little flowers 🤔
It is unfortunate that your beautiful flowers turned into someone’s late night snack. There must be some incredibly hungry animals living around your home. One culprit to cross off the potential list is deer because cosmos are a flower tend to avoid. Hopefully they did not eat too much of the plant so that it can continue to grow and more flowers will bloom this year.
I'm not sure how unusual this is, but our cosmos plant in the backyard measures exactly 12 feet high! I wish I could post a picture of it!
I live part of the year in Toronto, Ontario in Canada, and the other part of the year 200 kilometres north of Toronto, where cosmos are definitely annuals. But in Toronto itself, they seem to be perennials, coming back year after year near sidewalks, in sunny spots, in ground that is less than fertile, as happy as the proverbial clams. Not too many clams in Toronto, though. Wherever they grow, cosmos are very satisfactory, happy-making plants.
Very complete post about Cosmos, thanks.
I did grow them from seed and here is a photo post of the steps and results. There was one error I committed. Curious?
Thank you. I planted these many years ago and wanted some specific guidelines on growing cosmos. Thanks so much
