Perennial of the Asteraceae family, this yarrow is native to Greece and Macedonia, where it colonizes calcareous rocks, scree, and sun-exposed cliff fissures, at altitudes between 800 and 2,000 meters approximately. It is part of a small group of Balkan yarrows with solitary flower heads, very different from the common yarrows with dense corymbs.
It forms a compact and dense, silver-gray cushion, hardly exceeding 10 to 15 cm in height. The leaves are narrow, linear to spatulate, slightly toothed, densely tomentose, with a characteristic silver-gray that persists throughout the year and constitutes one of the plant's constant attractions, even when not in bloom.
The flower heads are borne individually at the top of slender stems, with widely spread white ligules surrounding a pale yellow, almost cream center. In its natural habitat, its flowering extends from May to July. In cultivation, it readily blooms from May to June, sometimes with a partial resurgence in summer.
It requires perfect drainage, full sun exposure, and a poor to moderately fertile soil. It fears stagnant winter moisture much more than cold. A choice plant for dry rock gardens, walls, and gravel gardens.
