The Carex comans ‘Frosted Curls’ is a genus from the Cyperaceae family and is commonly called hair sedge. The Carex comans ‘Frosted Curls’ is native to New Zealand.
The hair sedge forms grass-like tufts of very thin, long, silver green leaves that are curled at the top. The leaves lay untidily on the ground and create a untidy look. Or a playful look. It depends on how you look at it. For me it was the reason to remove the Carex comans ‘Frosted Curls’ from my garden.
Although the Carex comans ‘Frosted Curls’ may look like an ornamental grass it is not a grass.
The flowers do not have much ornamental value. The green/brown spikes and are usually shorter than the leaves. The Carex comans ‘Frosted Curls’ produces seeds and spreads with those. The seedlings are easy to remove if they grow in an unwanted spot so that is not a problem.
In mild winters the hair sedge is evergreen. With severe frost the leaves may wither but in spring new leaves will form. It is best to cut the leaves at about 4 inches (10 cm) above the ground in spring to make room for the new ones.
The Carex comans ‘Frosted Curls’ forms a tuft that gets wider over the years. You can dig it up in spring and divide it.
The hair sedge prefers well-drained moist soil. The Carex comans ‘Frosted Curls’ can grow in almost any soil and is reasonably salt tolerant. In too much sun or drought the leaves will wither. The Carex comans ‘Frosted Curls’ tolerates shade.
