Gypsophila paniculata aka Baby's Breath

Gypsophila paniculata, commonly known as baby's breath or panicled baby's-breath, is a tap-rooted perennial plant native to central and eastern Europe. This herbaceous perennial can grow up to 1.2m tall and wide, with slender stems and mounds of branching stems covered in clouds of tiny white flowers during the summer months. Its name "baby's breath" is derived from either the appearance of its delicate white flowers or the sour milk-like scent it emits. Baby's breath thrives in dry, sandy, and stony places, particularly on calcareous soils. It was first discovered by the Swiss-Russian botanist Johann Amman, who sent specimens to Linnaeus from St. Petersburg. This plant's airy form and numerous small flowers in white or pink make it a great addition to garden borders, providing an interesting contrast to larger flowers and dense shrubs. It can reach a height of 3 feet and width, or in dwarf varieties, 1 to 1 1/2 feet tall. Baby's breath is also prized for its use in cut flower arrangements and dried flower displays. While suitable for USDA zones 3 through 9, it can be invasive in certain regions.
