Forsythia and Calla lily 'Flamingo'.
The typical flowers for Girl's day, or Hinamatsuri on March 3rd., are pink Peach blossoms and yellow Rape flowers (Brassica napus). Pretty and humble, they are symbolizing youthful beauty and fertility. This festival is also called Momo no sekku, the Peach festival. In less traditional arrangements any pink and yellow flowers are acceptable.
In this contemporary ikebana arrangement without kenzan, I wanted to move away from the expectation of being pretty and humble and rather focus on girl power. At the flower market I found a bunch of unusual pink flamingo Calla lilies with powerful vertical lines - perfect for what I was aiming at.
