Gypsophilia paniculata L.
Baby’s breath is a deep-rooted perennial growing 3 to 4 feet tall. Its leaves are narrowly lanceolate, growing opposite up the slender stem. The numerous flowers, 6 to 8 mm wide, produce black seeds that are 1.5 to 2 mm long. The seeds are its primary way of reproducing. It prefers disturbed sites, but can thrive in sandy or open, grassy soil. It tolerates variations in moisture and temperature.
Baby’s breath is commonly used in floral arrangements, though it is considered an invasive in the Pacific Northwest. Because of its aesthetic popularity, it’s often found escaped from gardens or private cultivation. It can form dense stands and can be difficult to control. Plants, averaging around 14,000 seeds each, usually spread nearby with wind, but can break and tumble to greater distances.
