C Asia to Europe
There is some discrepancy between Europe and America in the naming of this species. Plants under this name may also be known as S. ×superba (S. ×sylvestris × S. villicaulis), the true hybrid having smaller leaves and forming smaller clumps. They are also listed under the name S. ×sylvestris L. (S. nemorosa × S. pratensis). As understood here, S. nemorosa flowers before it forms a clump and has blunt, wrinkled, often wavy-edged and ascending to clinging grey-blue leaves, while S. ×sylvestris forms basal clumps early and has pointed leaves that are greener, smoother and at right angles to the stem.
