Culture

Easily grown in organically rich, consistently moist soils in full sun to part shade. Plants need consistent moisture for full sun locations. Avoid deep shade. Plants will grow in very shallow water. Cut foliage to the ground in late winter. Propagate in spring by division. Plants slowly naturalize by rhizomes in optimum growing conditions.

Noteworthy Characteristics

‘Oehme’ is a clumping palm sedge that typically grows to 1-2’ tall and as wide on generally upright triangular stems adorned with horizontally radiating green leaves variegated with narrow yellow margins. Foliage superficially resembles a small palm tree, hence the common name. Leaves emerge medium green in spring, gradually acquiring thin yellow margins as the growing season progresses. Insignificant flowers appear in late May atop pointed yellow brown spikes which persist into fall. Species plants are native from Ontario to Manitoba south to Kansas, Missouri and Kentucky. Specific epithet is in reference to the Muskingum River in Ohio along which plants may be found. In Missouri, plants typically grow in swamps and flood plains along major rivers of the state. ‘Oehme’ is a sport reportedly discovered in the garden of landscape architect Wolfgang Oehme.

Problems

No serious insect or disease problems.
