Adenocarpus argyrophyllus

Shrub of the Fabaceae family, native to the Iberian Peninsula, where it is endemic to the mountainous areas of central and southern Spain, mainly in the Andalusian sierras and the elevations of the central system, where it grows on poor, well-drained siliceous soils, in open and sunny environments.

It forms a dense and bushy shrub, reaching 1 to 2 meters in height, with branches covered with trifoliate, small and tight leaves, whose underside and stems are covered with a silky silvery pubescence that earns it its epithet argyrophyllus — with silvery leaves. This downy and luminous aspect gives the entire foliage a characteristic silvery-gray sheen, particularly visible when the breeze stirs the branches.

The flowers are typically papilionaceous, of a bright and clear yellow, grouped in dense terminal clusters that abundantly cover the shrub at the time of flowering, from May to June. The contrast between the intense yellow of the flowers and the silvery foliage is particularly striking.

In cultivation, it requires full sun and a very well-drained soil, poor to ordinary, dry in summer; it is not well-suited to heavy, calcareous soils or those subject to prolonged winter moisture. Its hardiness is moderate, acceptable in regions with mild winters, but needing protection in colder climates.

It is suitable for Mediterranean gardens, silver plant massifs, and natural spirit compositions on dry soils.
