Cultivar selected from Achillea tomentosa , sharing the same creeping and low habit, the same finely pinnate and woolly gray-green foliage, and the same cultural requirements: full sun, very well-drained soil, dry in summer.
It is distinguished from the type species by the shade of its corymbs, a deeper and more intense yellow, often described as golden yellow, which enhances the contrast with the silvery foliage. The difference remains subtle depending on the growing conditions and light, but the hue of the capitula is noticeably warmer and denser than the type.
Flowering occurs from May to July, under the same conditions as the species. It is suitable for the same uses: rock gardens, dry borders, sunny walls, where it forms persistent flowering cushions.
