Cosmos are one of the easiest annual flowers to grow.
Just scuff some dirt over a seed in late May, water regularly and by the end of June or early July you have a 2 foot plant that is beginning to bloom.
I’ve found that Cosmos tend to grow about 3 to 4 feet tall by up to 3 feet wide in my garden. They usually bloom for me until the end of September or early October in my Zone 6 garden.

Lovely pic. My daughter said it was very pretty.
Thanks for more info too. I didn’t realize how big they would get.
Although a Cosmo drink would sound so refreshing right now!
Enjoy the rest of your Sunday!

Yes I never thought they’d get quite that big either. My parents cosmos in a zone 5 garden only every got to be 2.5 to 3 feet tall by maybe 2 feet in diameter, but mine always seem to turn into giants.
Tricia’s Musings http://www.feverishthoughts.com has a Green Thumb entry as well. 🙂

I used to have cosmos at our old house. I don’t know why I didn’t think of them for here. Too late for this year but I’ll ahve to remember for next year. They are beautiful aren’t they.

I grew cosmos one year and they practially took over, so I am more cautious with them. They are beautiful though. Love the gardening stuff.
