Perennial of the Fabaceae family, Astragalus danicus is a Eurasian species with a wide distribution, present from Northern and Central Europe to Siberia and Central Asia. In Europe, it favors dry limestone lawns, exposed slopes, lean meadows, and steppe edges, generally in plains or low mountains.
It forms small, spreading clumps, not very tall, rarely exceeding 20 to 30 cm, with finely pinnate foliage composed of numerous oval leaflets of a medium green, slightly hairy. The habit is supple and natural, without the spiny rigidity of Mediterranean astragals.
The flowers are papilionaceous, of a fairly bright pink-purple to purple, gathered in short and dense clusters that rise above the foliage. The color, clear and bright, contrasts pleasantly with the tender green of the pinnate leaves.
In its natural habitat, its flowering extends from May to July. In cultivation, it generally occurs from May to June.
It requires full sun and well-drained soil, dry to fresh, preferably limestone. Like most legumes, it fixes atmospheric nitrogen thanks to symbiotic bacteria and adapts perfectly to poor soils. Hardy and undemanding, it is suitable for sunny rock gardens and natural character dry lawn gardens.
