Taste, aroma & texture
Two species — two different profiles. *Cosmos bipinnatus* (pink, white, purple) — delicate, slightly grassy and green, practically neutral without pronounced bitterness; one of the most delicate flavors among summer edible flowers. *Cosmos sulphureus* (yellow and orange) — bitter, spicy, herbal with a hint of pepper; resembles some varieties of chrysanthemums or marigolds. The leaves of both types are edible, but very bitter - they are not used.
Tender, slightly green-herbaceous in *C. bipinnatus*. *C. sulphureus* is spicier, with a light peppery note. Neither species is strongly scented—fragrance is not the flower's main asset. The stems smell quite sharp and green when broken - another reason not to use the stems.
The flowers of the inflorescence are "baskets" with 7-8 broad tongue-shaped petals around a yellow or orange disc. Petals are thin, soft, delicate - silky to the touch. Flower size *C. bipinnatus* — 5–8 cm, one of the largest edible flowers in the catalog. This makes it a spectacular decoration for large dishes and cakes. *C. sulphureus* — somewhat smaller, 3–5 cm.

Culinary use
Cosmeia is primarily a decorative ingredient — large, delicate pink and purple petals C. bipinnatus provide one of the most elegant flower decorations among annual plants. Unlike small flowers (viola, balsam), cosmea is large enough to become the centerpiece of a presentation. For those who want a more pronounced taste - C. sulphureus with its spicy-bitter profile.

a whole flower or individual petals are placed on the dish immediately before serving. Large size C. bipinnatus gives an impressive result with minimal effort.

Infusion in syrup
petals are poured with hot sugar syrup (1:1); infuse for 30–60 minutes; a pink or white shade turns into syrup; for watering desserts and drinks.
Drying
the petals are laid out in one layer on parchment and dried at 35°C or in the shade; retain their shape and delicate pink color; used as a topping for desserts and tea mixtures.

Cosmos bipinnatus is a native species of Mexico and Central America, where it was eaten before the arrival of the first Spaniards. Name Cosmos comes from the Greek "order, beauty" - it was given to the plant by the Spanish botanist Antonio José Cavani in 1791, impressed by the symmetry of the petals.
Kosmea came to Japan in the 1880s and became so ingrained in the culture that it became one of the basic flowers of the autumn landscape of Japanese literature and painting. In Tokyo's Hamarikyu district and in Saitama Prefecture, there are entire parks of kosmeia — millions of plants that bloom in October.
