Perennial of the Asteraceae family, native to the Balkans, mainly Greece and North Macedonia, where it grows on limestone rocks, screes, and exposed slopes, from colline to alpine levels.
It forms low, spreading clumps, reaching 10 to 20 cm in height, with persistent foliage of a bright silvery gray. The leaves, entire to slightly toothed, narrow and lanceolate, are densely covered with a whitish indumentum that gives them this characteristic hue and constitutes an adaptation to the hot and dry conditions of its natural habitat.
The flowers are gathered in white capitula, with a white heart as well, grouped in loose and elegant corymbs above the foliage. Unlike many yarrows, the contrast between the silvery foliage and the pure white flowers constitutes here the essence of the ornamental effect.
In its natural habitat, its flowering extends from May to July depending on the altitude. In cultivation under our latitudes, it blooms in May-June.
It is cultivated in full sun, on well-drained, poor, and preferably limestone soil. It is particularly suitable for rock gardens, walls, and dry gardens, where its silvery foliage remains decorative all year round.
