Cosmos Flowers

Native to Mexico, Cosmos (Cosmos bipinnatus and Cosmos sulphureus) are tall, airy plants bearing daisy-like flowers in shades of pink, white, orange, and red. Their finely divided foliage gives them a delicate, ferny appearance.

The name “cosmos” comes from the Greek word meaning “order” or “harmony“, inspired by the flower’s perfectly symmetrical petals. Mexican farmers grew cosmos as ornamental plants long before they spread globally. They flourish in poor soils, reflecting their origins in Mexico’s semi-wild fields. Cosmos are culturally linked to Dia de los Muertos (Day of the Dead) decorations due to their late summer to fall blooming.

Cosmos is a species of flowering in the Asteraceae (sunflower) family native to the meadowland and scrubland of Mexico, where most species are found. While there are 20 recognized cosmos species[1], two annuals, Cosmos bipinnatus, and Cosmos sulphureus, are best known to home gardeners.
