Perennial of the Fabaceae family, widespread in the mountains of Central and Southern Europe, from the Alps to the Carpathians and the Balkans. It frequents alpine meadows, stabilized scree, snow hollows, and poor grasslands on various substrates, generally between 1,500 and 2,800 meters.
The plant forms a low, spreading tuft, reaching 10 to 20 cm in bloom. The leaves are trifoliate, with oval-oblong leaflets, finely toothed, of a fresh and slightly shiny green, borne on slender, ascending stems.
What immediately distinguishes this species from most alpine clovers is the color of its spherical to ovoid heads. Bright yellow at anthesis, they gradually turn to orange and then to a deep reddish-brown, almost chocolate, as they age, so that a single plant simultaneously bears heads at all stages of this colorful transformation. This chromatic change, linked to the drying of the persistent corollas after flowering, is one of the most singular spectacles of summer alpine meadows.
In its natural habitat, its flowering extends from July to August. In cultivation, it requires well-drained, cool soil in full sun and tolerates poor substrates. It is suitable for mountain-inspired rock gardens and reseeds modestly.
