Cosmos bipinnatus (Click on photo for a larger view)

My flower gardens would not be complete without cosmos. The name cosmos was bestowed by Spanish priests who grew them in their mission gardens. Cosmos are of the family Compositae and there are some 20 different cultivars; however, Cosmos sulphureus and Cosmos bipinnatus are the two most often grown in home gardens. You can easily tell the difference between the two by the leaf structure. Cosmos sulphureus has leaves that are long with narrow lobes and hairy margins. In contrast, Cosmos bipinnatus has a fine lacy threadlike appearance. Cosmos bipinnatus is the variety that I prefer to grow in my gardens.

Cosmos are very easy to grow and the seeds can simply be broadcast over the area. Seeds will germinate in 7 to 10 days if the soil is fairly warm; 24C (75F). Cosmos like an alkaline soil with a ph between 6.0 and 8.5; which reflects their native region of Central America. Cosmos prefer a soil that is not overly rich and can tolerate drought well. Full sun is best; however, cosmos can also do well with some shade.
