Achillea ptarmica 'The Pearl', commonly known as Sneezewort or The Pearl Yarrow, is a hardy, herbaceous perennial valued for its delicate, button-like white flowers and feathery foliage. It typically grows to a height of 50 cm with a spread of about 50 cm, forming a clump of slender, lance-shaped green leaves. From early summer to autumn, it produces abundant clusters of small, double white flowers, resembling miniature pom-poms, which attract pollinators. It is commonly used in cottage gardens, borders, and wildflower meadows and is also popular for cut and dried flower arrangements due to its long-lasting blooms.
