Are cosmo flowers from a bulb or seeds?
The Cosmos flowers are started from seeds.They come in various colours and heights. After flowering let seeds ripen, collect, keep seeds in cool place and sow again for a sea of flowers next year. The plants require sun, and are happy in light poor soil.

Reply:Seeds. They grow great in Southern California and the nice part is that they reseed themselves.
Reply:I buy seeds every year and in the fall, they die off. I replant each spring.
Reply:Seeds, and they readily self-sow, or you can save the seeds and replant next year.
Reply:Cosmos grow from seed. If you plant them in your garden in the right conditions (lots of sun and regular watering, average garden soil), they will reseed themselves and you will have more the next year.
