Perennial from the Cyperaceae family, Carex morrowii is native to Japan and Korea, where it grows in cool and shaded undergrowth, on well-drained soils that retain some moisture. The 'Ingwersen' selection is one of the most refined variegated forms of the species.
It forms dense, evergreen clumps with a rounded and regular habit, reaching 30 to 40 cm in height. The leaves are narrowly linear, rigid, with a glossy dark green center, bordered by a remarkably sharp cream to ivory white edge. This fine and precise marginal variegation gives the clump a particular brightness, very effective in shaded situations where few plants offer such winter brilliance.
The floral spikes are discreet, pale brown, borne on slender stems slightly exceeding the foliage. The main interest of this sedge lies in its evergreen and architectural foliage, which remains ornamental all year round.
In its natural habitat, its flowering extends from April to May.
It thrives in cool, humus-rich, well-drained soil, in shade or partial shade. It tolerates limestone and withstands periods of moderate drought once well established. Hardy and undemanding, it is suitable for woodland borders, pot compositions, and Japanese-style gardens.
