When to plant Variegated Japanese Sedge
Japanese sedge is a clump-forming, evergreen perennial sedge often grown in its variegated cultivars for shade gardens. NC State propagates it by division and seed and describes it as an easy, trouble-free sedge, so set out new plants or divisions in spring as growth resumes. It grows in moist, acidic soil in any light, though a full-sun site needs constant moisture.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
