One of the most beautiful, and spectacular flowers, that has ever existed is without any doubt the anemone. Anemone is a genus of flowering plants in the buttercup family Ranunculaceae. Species of anemone can grow up to 1.2 meters (4 feet) tall. This is because the anemone flowers close up at night and open back up in the morning. According to the Victorian language of flowers, anemone flowers also signify fragility.
