Yellow Yarrow (Achillea filipendulina) – Elegance and Resilience
Description
Yellow yarrow (Achillea filipendulina), also known as fern-leaf yarrow, is a hardy perennial from the Asteraceae family. Native to the mountains of the Caucasus and Southwest Asia, it is highly valued for its abundant and long-lasting blooms, as well as its ability to thrive in challenging soils.
This perennial produces finely cut, fern-like foliage with a musky scent when crushed. In spring, it develops a dense rhizomatous base, helping to prevent weeds. From June to October, its upright stems bear bright yellow flower clusters (dense corymbs) up to 15 cm (6 in) in diameter. A highly nectar-rich plant, it attracts numerous pollinators and can self-seed naturally.
