About this plant
A delightful borderline tender sedge that has appealing flowers. This has long slender green stems that will be up to 60cm in height and which have a running habit of growth, so is best confined to a container. The flowers are carried at the stem top and consist of long extended leaves coloured white at their base, green in their outer portion, and carrying a cluster of tiny 'flowers' from brown bracts. They appear very like large flying insects when seen at any distance. They are a feature in mid-to-late summer. The stems can be cut and dried for flower arrangements. This is happy in very moist or boggy soil or in water up to 3cm deep. This is not hardy throughout the country, though it can be lifted for winter and kept in a frost free environment in a container, regularly watered.

Protect from winter cold
Bring the plant into a frost-free area before frosts occur, and do not put them outside until all danger of frost is past. Follow watering instructions, or allow the plant a period of dormancy during the winter.
Plants need to be brought inside in cold areas, i.e. colder than zone 8.
