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.
