White-flowered form of the alpine clover, a perennial from the Fabaceae family. The type species is native to the Alps, the Pyrenees, and the Northern Apennines, where it colonizes high-altitude acidophilous grasslands, nard heaths, and siliceous rocky slopes, generally between 1,500 and 2,800 meters. It is characteristic of acidic, poor, and well-drained substrates.
The plant forms a low and spreading tuft, hardly exceeding 5 to 10 cm in height, with short stems bearing trifoliate leaves with narrowly lanceolate leaflets and a deep green color, giving it a finer and more elegant foliage than common meadow clovers.
The flowers are gathered in dense globular heads, borne on short stems. In this 'Album' form, they are pure white to slightly greenish in bud, with distinctly elongated standards giving the capitula a looser and more starry appearance than the pink type form. The flowers emit a slight fragrance.
In its natural habitat, the flowering of the type species extends from June to August depending on altitude. In cultivation, this form generally blooms in June-July. It requires an acidic or neutral, very well-drained, poor soil, in full sun — insufficient drainage is quickly fatal to it. It is not suitable for calcareous substrates. Its hardiness is otherwise excellent.
