What is the meaning of the yellow cosmos flower? It is said to be **"wildness"**.

It belongs to the Asteraceae family and is native to Mexico, among the countries of South America. It was originally introduced as an ornamental plant and has spread to grow wild. In addition to single flowers, there are also double flowers and semi-double flowers.

Yellow cosmos was introduced to Korea in 1930-1945 and is cultivated as an ornamental plant. It has become partially wild and the flowers bloom from July to September.

But don't you wonder what's different about it from the general cosmos? First, the color of the flower is different. That's why it's also called yellow cosmos or yellow cosmos. Ordinary cosmos bloom in a variety of colors, including white, pink, and deep pink. However, they are not called pink cosmos, white cosmos, or red cosmos, but simply cosmos. But yellow cosmos has a separate name.

First of all, the difference is in the thickness of the leaves. The leaves of ordinary cosmos are less than 2 mm thick, thinly divided like threads, and produce white, pink, and deep pink flowers. However, yellow cosmos has leaves that are somewhat widely divided like mugwort or chrysanthemum, and produce yellow or orange flowers.

Secondly, the flowering period is different. The flowering period varies depending on the sowing period, but cosmos can be seen from late spring to autumn. Yellow cosmos, however, has the characteristic of being seen from summer to early autumn.

Therefore, the two plants are similar but completely different plants, classified as the species cosmos and yellow cosmos.

Isn't that amazing? They look so alike, so I thought they were the same species, but they are completely different species.

There is not only cosmos but also Coreopsis grandiflora, which is similar to yellow cosmos. This flower blooms from late spring to summer, so its flowering period is similar to that of yellow cosmos and can be confusing. It has the same yellow flowers and similar flower shapes, making it difficult to distinguish immediately. The difference is that while cosmos or yellow cosmos have divided leaves, Coreopsis grandiflora has leaves that are not divided.

Today, we learned about yellow cosmos. We also compared it with ordinary cosmos and Coreopsis grandiflora. After comparing it with these other plants, don't you feel like you know yellow cosmos well?
