Gypsophilia, also known as Baby's Breath, has traditionally been the most popular filler flower used in centerpieces and bouquets; but, it is now gaining widespread popularity massed on its own to create simple, relaxed arrangements perfect for farm, country, or wildflower weddings and events. For a modern twist, try submerging it underwater in a tall vase. Gypsophilia's airy branches are covered in small, white flowers, that blend well into any type of floral design. It is a very hardy flower with a long vase life that does well in any type of environment.
