한국에서는 스승의 날이나 어버이 날에 카네이션을 선물한답니다. In Korea, we give a carnation to a teacher or parents for their day like teacher’s day or parents’ day. (to express how much we thank to them)
And then they wear a red carnation on their breaston that day like a corsage.

그리고 하얀 국화는 돌아가신 분들에게 드리고요.
and a white chrysanthemum for the dead.
