Paronychia argentea

Paronychia argentea Lam. — Perennial of the Caryophyllaceae family, widely spread throughout the Mediterranean basin, from the Iberian Peninsula to the Near East, including the Maghreb, southern France, and the Italian peninsula.

It colonizes open and well-drained environments, dry lawns, garrigues, rocky embankments, and coastal sands, on poor substrates, often calcareous or siliceous, from sea level to moderate altitudes.

The plant forms sprawling, prostrate mats, barely exceeding 1 to 2 cm in height, with stems extending horizontally to gradually cover the ground. The leaves are small, oval-elliptical, a fairly bright green, clearly visible between the floral glomerules. It is the scarious bracts that dominate the appearance of the plant in bloom: broad, translucent, almost glassy, with a bright silvery white, they envelop the small glomerules and give them a unique pearly and crumpled appearance, quite different from the matte white of other Paronychia.

In its natural habitat, flowering extends from May to July depending on the latitude. In cultivation, it can begin as early as April in a warm exposure.

It requires a perfectly drained, lean soil in full light and easily withstands summer drought. Sensitive to excess moisture in winter, it naturally integrates into a sunny rock garden or between the slabs of paving.
