Knotted Cranesbill (Group) (Geranium nodosum) refers to cultivated selections of this adaptable perennial, chosen for their delicate flowers, shade tolerance, and long blooming season. These grouped varieties share the species’ signature five-petaled blooms, typically in shades of soft pink to violet-purple, often with fine veining that adds subtle detail. The flowers are borne above glossy, three-lobed green leaves, which form a tidy, low mound.

Native to southern and central Europe, Geranium nodosum naturally inhabits woodland edges, shaded slopes, and grassy clearings, thriving in dappled light where many other perennials struggle. Group cultivars may differ in flower color intensity, size, or foliage tone, but all retain the plant’s understated elegance and ability to flower from late spring into autumn. The common name “knotted cranesbill” refers to the slightly thickened nodes along its stems. Valued for its resilience, pollinator appeal, and compatibility with companion plants, this group brings dependable color and texture to shaded and semi-shaded gardens.
