Burning sun yellow cosmos (Cosmos sulphureus) are vibrant, daisy-like flowers with bright yellow petals and sunny centers that bloom generously in gardens. They attract pollinators like bees and butterflies, supporting biodiversity, and their cheerful color adds a lively accent to borders, beds, or containers. These annuals are also useful for filling gaps in mixed plantings or creating informal, naturalistic displays. Their seeds can be harvested for replanting, ensuring a low-maintenance, cost-effective addition to any garden.

ADDITIONAL SOWING INFORMATION

GROWERS TIP

Cosmos are best established directly outdoors. The seed can be scattered to the surface of the soil and lightly covered. These cosmos plants typically grow over 2 feet so they are best planted along fences, in the background, or in a naturalized setting.
