In the garden

Carex divulsa is a clump-forming, grass-like member of the sedge family with evergreen leaves and a compact habit, reaching 0.5–1 metres tall and wide. Flowering takes place from May to July, producing upright inflorescences above the foliage. Allow 2–5 years for plants to fill their eventual spread. Plant where it will receive anything from full sun to full shade; it adapts to chalk, clay, loam or sand and thrives across acid, alkaline or neutral soils. Soil moisture can range from well-drained to poorly drained, including moist but free-draining situations. It suits west-, south-, north- and east-facing aspects and will tolerate both exposed and sheltered sites. In UK hardiness terms it falls within H5–H7 (hardy to fully hardy), so it withstands typical outdoor conditions across most of the country. Use Carex divulsa in cottage and informal borders, gravel or prairie schemes, coastal plots and wildlife gardens, and it is equally at home in patio containers. Its evergreen tussocks give structure through winter while flowering spikes appear in late spring to mid-summer. For long-term planting, monitor for congestion as the clumps establish over several seasons.
