What does Cosmos look like?
Cosmos plants are annual or perennial herbs that grow between 0.3 and 2 metres tall. Their leaves are either simple or finely divided, arranged in pairs on the stem. The flowers form a central disc surrounded by a ring of broad petals, much like a daisy. The color of the flowers varies widely across the different species and cultivated varieties, making them popular in gardens for their bright, jewel-like appearance.
Where does Cosmos come from?
Cosmos is native to scrub and meadowland throughout the Americas, stretching from Colorado and Missouri in the United States, through Mexico (where most species are found), Central America, and as far south as northern Argentina. The genus was later introduced to other regions, such as the high plains of eastern South Africa, where it spread after contaminated horsefeed was brought during the Anglo-Boer War.
When and how Cosmos blooms
Cosmos flowers grow from seed and thrive in open, sunny spots with well-drained soil. They bloom in a variety of climates, depending on the species, and are often grown as annuals in gardens. The plants produce their daisy-like flower heads on tall, slender stems, and many hybrids and cultivars have been developed for ornamental use.
How Cosmos is used
Cosmos is widely planted as an ornamental in gardens for its attractive flowers. In Maritime Southeast Asia, especially in Malay and Sundanese cuisine, the leaves and young shoots of Cosmos caudatus and C. sulphureus are eaten raw in salads called ulam and lalab, served as appetizers. Some species have also become part of the wild flora in places where they have been introduced.
Kinds of Cosmos
There are at least 35 species of Cosmos, with the highest diversity in Mexico. Gardeners have selected many hybrids and cultivars for their varied flower colors and forms. Some species, like Cosmos bipinnatus, have become naturalized outside their native range, especially in North America and South Africa.
What Cosmos means
The name Cosmos comes from Greek, possibly referring to the orderly arrangement of the flower parts or to their jewel-like colors. While not tied to a particular symbolism in the sources, Cosmos is valued for its beauty in gardens and its use as an edible herb in Southeast Asian salads. Its spread to new continents is linked to historical events such as the Anglo-Boer War.
