Japanese Cornel Cherry, a birthday flower of February 21st

One of the most beautiful flowers in Japan in spring is the Japanese Cornel/ian Cherry, known as sanshu in Japanese. It is so beautiful it is known by the nickname "haru-kogane-bana" "春黄金花", which literally means "spring's golden flower".  In the right setting, it truly looks golden.

The tree flowers around March to April in Japan. In the hanakotoba, Japanese language of flowers, it means “endurance” “持続,” “durability” “耐久,” and “steadfast love” “気丈な愛”. The meanings come from its long‑valued medicinal fruit, known for strengthening the body. 

It is one of least three birthday flowers of February 21st annually in Japan. The other two I know of are Violet and Nemophila. Cornel/ian Cherry is also the birthday flower of March 17th.
