About Woolly yarrow
Achillea tomentosa, also known as woolly yarrow, is a low-growing perennial herb valued for its finely divided, woolly, grayish-green foliage that forms an attractive mat. During summer, it produces flat-topped clusters of small, bright yellow flowers, attracting pollinators. It is ideal for rock gardens, sunny borders, or as ground cover in dry, well-drained areas.
Native range
Europe, from Spain to Scandinavia and Russia
Care tips
It requires full sun for optimal flowering and healthy development. Watering should be moderate, allowing the substrate to dry out completely between waterings, as it is drought-tolerant once established. It prefers light, well-drained, and nutrient-poor soils; avoid heavy, wet soils to prevent root rot. A common mistake is overwatering, which can be fatal for this drought-resistant plant.
