A light and airy perennial, ‘Cotton Ball’ produces clouds of soft, fluffy white flowers held above finely textured blue-green foliage. Blooming in early to mid-summer, the delicate blooms resemble floating cotton puffs and add height, movement, and an ethereal quality to borders and mixed plantings.
