A perennial of the Geraniaceae family, Geranium pylzowianum is native to western and central China, notably Sichuan, Gansu, and Tibet, where it grows in alpine meadows, grassy screes, and rocky slopes, between 2,500 and 4,500 meters in altitude.
It is a small plant, barely exceeding 15 to 20 cm, with a low and spreading habit. It develops slender, stoloniferous rhizomes, producing small tufts of finely cut foliage, with narrow and deeply divided segments, of a bright and delicate green.
The flowers, relatively large compared to the plant, are a bright pink to deep magenta pink, with widely open and rounded petals, traversed by dark veins radiating from a well-visible, greenish and hairy center. This contrast between the tufted center and the smooth, bright petals is one of the most characteristic features of the species.
In its natural habitat, its flowering extends from June to August. In cultivation, it generally occurs from May to July.
Its stoloniferous nature allows it to gradually colonize the crevices of a rock garden, without becoming invasive. It requires well-drained, light soil, in full sun or very light partial shade. A precious species for small alpine rock gardens, delicate in appearance but robust in practice.
