Rosette

A rosette, a stylized, flower-shaped decoration often presented as an award with a ribbon or (military) medal. Appears as a motif in ancient cultures. Generally depicted as a circular, yellow-and-orange flower.

Commonly used for Valentine’s Day, Mother’s Day, and other special occasions. May be more generally used to express such ideas as love, happiness, and beauty. Also used as a yellow accent color.

Not to be confused with 🌼 Blossom, though their applications may overlap.

WhatsApp's rosette is orange, white, and purple; Twitter's is purple and blue. Samsung's was previously pink. A non-emoji Unicode character 🏶 Black Rosette was once shown as an emoji on LG phones.
