Are cosmos flowers annual or perennial?

Answer

Cosmos are annual flowers. This means that they must be replanted or resown each year; their plants will not survive beyond the blooming season, which, according to Cornell University, typically ends at the time of the first frost.

Cosmos produce long stalks topped by bright pink, red, purple and white flowers and lacy green leaves. They make good cut flowers and are also effective as fill-in plants for a wildflower field. They typically spread between 1-2 feet and can grow as tall as 6 feet. They are also aggressive seeders, making it easy to collect seeds for next year's blooming season.
