Notes: Cosmos are popular garden flowers known for their airy, daisy-like blooms in various colors, including white, pink, red, and purple. Due to their long-lasting blooms, they are often used in cottage gardens, wildflower gardens, and as cut flowers. Cosmos are low-maintenance, fast-growing, and can reseed themselves in the garden. They attract many pollinators and are considered a great addition to pollinator-friendly gardens.
