Achillea ptarmica ‘Peter Cottontail’ is a herbaceous perennial with an upright, compact habit and finely textured foliage. This ornamental cultivar of sneezewort yarrow is valued for its abundant double white flowers, long blooming period, and ability to attract pollinators.
The foliage consists of narrow, finely divided, dark green leaves that form a dense mound at the base of the plant. From summer into early autumn, upright stems carry clusters of rounded, double white flowers that create a soft, elegant appearance. The flowers are excellent for borders and are attractive to bees and butterflies.
Achillea ptarmica ‘Peter Cottontail’ prefers full sun and well-drained soil. It adapts well to average garden soils and tolerates moderate drought once established. It performs best in sunny perennial borders, cottage gardens, mass plantings, containers, and cut flower gardens.
