Happy Leap Year Day!

Perhaps we should include a little something extra?

Please forgive me if my Flower of the Day submissions come across as formulaic: (1) Regular shot; (2) Macro; (3) Black and White. Why is there so much power in the number three? The example abound. Probably the most powerful example would be the Holy Trinity (Father, Son, and Holy Spirit.) Another is the adoption of the three movement convention in Classical music that was developed by one of my favorite composers, Antonio Lucio Vivaldi; that is, fast, slow, fast. Can you think of other examples of the power of three?
