Perennial of the Geraniaceae family, Erodium triflorum is native to the Near East and the Anatolian peninsula, where it grows on rocky slopes, garrigues, and sunny dry lawns. It is a little-known species outside specialized collections, yet it deserves a full place in character rock gardens.
It forms a low and spreading tuft, rarely exceeding 15 to 20 cm in height, with a semi-prostrate habit. The foliage consists of rounded to slightly lobed, crenate leaves, of a fairly strong medium green, covered with a fine pubescence that gives them a slightly velvety feel to the touch. The floral stems are erect, generally bearing two to three flowers per umbel, which the species name directly recalls.
The flowers are white to pinkish-white, with the two upper petals adorned with a large bright carmine-pink patch, clearly defined and traversed by darker veins. This contrast between the pure white of the lower petals and the colored spot of the upper ones is particularly sharp and gives the flower an animated appearance. In its natural habitat, its flowering extends from May to July. In cultivation, it can bloom from May to August.
It requires well-drained, light soil, in a sunny exposure. Hardy in regions with mild winters, it appreciates protection against excessive moisture in the cold season. Perfectly suited for rock gardens, walls, and alpine troughs.
