Erodium corsicum

A perennial of the Geraniaceae family, Erodium corsicum is endemic to Corsica and Sardinia, where it colonizes rock crevices, coastal screes, and rocky lawns on granitic substrate, from sea level to the lower mountain levels.

The plant forms a sprawling, loose carpet, 8 to 15 cm in height, with creeping, branched stems. The foliage is one of its most immediate attractions: small, rounded, crenate leaves, of a grayish-green, densely covered with a whitish down that gives them a velvety and silvery appearance. The leaf margins often take on reddish to purplish hues, especially in dry or cold conditions.

The flowers, borne on slender peduncles, are pale pinkish-white to pale lilac pink, traversed by fine pink-violet veins radiating from the center — a feature clearly visible on individuals with more intense flowering. In its natural habitat, its flowering extends from March to June; in cultivation under temperate climates, it can continue into summer with autumnal reblooms.

It requires full sun, perfectly drained soil, preferably stony, and good protection against stagnant winter moisture. It is a plant for troughs, walls, or sloping rock gardens, where its silvery foliage draws attention even when not in bloom.
