Purity white cosmos (Cosmos bipinnatus) are delicate, daisy-like flowers with bright white petals and sunny yellow centers, blooming abundantly from summer to fall. In gardens, they add a soft, airy aesthetic to borders, cottage-style plantings, or mixed flower beds, pairing well with vibrant perennials. Their nectar-rich blooms attract pollinators like butterflies and bees, supporting local ecosystems. They also make excellent cut flowers for fresh or dried arrangements, bringing elegance to indoor displays.

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. The plants typically grow over 3 feet so they are best planted along fences, in the background, or in a naturalized setting. Cosmos become rather drought tolerant as they grow taller and require a minimum temperature of at least 65F. Fairly deer resistant.
