Oriental Paper Bush, a birthday flower of March 20th

There are at least three different birthday flowers of March 20th annually. They include the yellow tulip, sweetpea and oriental paper bush. The latter is called Mitsumata  (ミツマタ / 三椏) in Japanese. Its scientific name is Edgeworthia chrysantha. 

Oriental paperbush, is a quiet but deeply symbolic presence in the Japanese landscape. The hanakotoba, Japanese flower language, are “strength” and “family bonds,” meanings that come directly from the plant’s character. The bark contains remarkably strong fibers prized for making high‑quality washi and even banknotes, giving rise to the idea of inner resilience. Its branching pattern, each stem naturally dividing into three, has long been compared to the connection between parent and child, a gentle metaphor for ties that hold steady even as life grows outward.

In Japan, mitsumata typically blooms from March to April, but it's not uncommon to see them starting to bloom in February either. The flower heads appear before the leaves - they are small globes of soft gold or orange. You can also see a photo and information about Oriental Paper Bush on this post by Tonetoedo.
