Cosmos is a genus, with the same common name of cosmos, consisting of flowering plants in the sunflower family.

Growth characteristics of this plant include:

Germination takes between 7 and 10 days at the optimal temperature of 75 degrees Fahrenheit (24 °C); flowering begins between 60 and 90 days after germination
It prefers a soil pH between 6.0 and 8.5, reflecting its native habitat in the alkaline regions of Central America
Flowering is best in full sun, although partial shade is tolerated

Excessive rain can cause cultivation problems, due to the delicate nature of the stems. Heavy rain can cause breakage. Cosmos bipinnatus can tolerate heat as long as adequate moisture is provided, however, it does not handle droughts, strong winds or cold temperatures well. Snails, slugs and aphids have a taste for Cosmos bipinnatus. Successfully cultivated plants can mature 2 to 4 feet x 12 to 18 inches.

The flowers of Cosmos bipinnatus attract birds and butterflies, including the monarch butterfly. It can be part of butterfly gardening and pollinators-honey bee habitat gardens.
