There are more than 20 different species of Cosmos. Two are native to North America while the rest are not. It is terribly confusing trying to determine native range using the word Cosmos when there are 26 different species of Cosmos plus many cultivars. The cosmos most frequently sold at nurseries are Cosmos bipinnatus and C. sulphureus. These cheery little plants are indigenous to South and Central America-

Our native Cosmos are parviflorus and caudatus. They are indigenous to the southern states.
