Perennial of the Geraniaceae family, Erodium x variabile is a horticultural hybrid resulting from the cross between Erodium corsicum, native to Corsica and Sardinia, and Erodium reichardii, endemic to the Balearic Islands. The 'Bishop's Form' cultivar is selected for the quality and intensity of its flowering.
The plant forms a dense, spreading cushion, 8 to 12 cm in height, gradually covering stones and rockery crevices. The foliage is evergreen, composed of small, dark green leaves, crenate and slightly rough to the touch.
The flowers, borne individually on slender peduncles, are bright pink to magenta pink, marked with darker veins radiating from a white center — a characteristic detail of the cultivar. In its natural habitat, the flowering of the parent species extends from spring to summer; in cultivation, 'Bishop's Form' blooms generously from May to September, with almost continuous production in mild weather.
It thrives in full sun, in well-drained soil, even rocky and poor. Sensitive to stagnant moisture in winter, it appreciates the protection of glass or an awning in very rainy conditions.
