Why We Grow It
Why We Grow It
Achillea ptarmica is an excellent addition to food forests and integrated perennial plantings due to its ability to attract pollinators, stabilize soil, and provide habitat for beneficial insects. It brings valuable minerals to the soil surface in a bioavailable form. Its tolerance for poor soils and drought conditions makes it a resilient choice for degraded landscapes or areas prone to erosion. Can help outcompete weeds at the base of your other taller perennials.

Additional Info
Achillea ptarmica has a long history of use in European herbal medicine, particularly for treating colds and respiratory issues—hence the name "Sneezewort." A preparation is made to snuff up the nose and cause sneezing. It is a type of yarrow so can be considered a dynamic mineral accumulator. Its flowers are highly attractive to pollinators, supporting bees and butterflies in ecological systems. In permaculture and agroforestry, it serves as a beneficial companion plant, improving soil health with its extensive root system and deterring pests. Its low-maintenance nature and ornamental value also make it a popular choice for naturalized gardens and wildlife corridors.
Achillea ptarmica, commonly known as Sneezewort or Pearl Yarrow, is a hardy perennial celebrated for its feathery foliage, delicate white flowers, and versatility in temperate climates as an easy growing groundcover. A resilient and low-maintenance plant, it thrives in diverse conditions, contributing to pollinator support and as a medicinal herb for your own apothecary. Spreads from underground runners but not can be easily managed. Great for pairing with shrub, understory and overstory trees.
