Plant in cool full sun to shade in a well-drained soil and irrigate regularly. Cold hardy to around 0 degrees F. This plant makes a bold statement as a container plant, as an accent, a border planting, or as a large scale groundcover in the landscape. Useful on the edge of the water garden but dislikes complete submersion.

This plant is a mutation of the popular Carex oshimensis 'Evergold' (a plant once called Carex morrowii 'Aurea-variegata') which has leaves with green margins on a central stripe of cream white. It was discovered in a tissue culture laboratory in Ireland in August 2006 by Pat FitzGerald of FitzGerald Nurseries of Kilkenny, Ireland. Under the cultivar name 'CarFit01' it received U.S. Plant Patent 20,955 on April 27, 2010 and was the winner of the Silver Medal at the Plantarium 2008 in in Boskoop Netherlands. We grew this nice sedge cultivar from 2010 until we closed the nursery in 2025 and also grew the yellow variegated cultivar Carex oshimensis 'Evergold'.
