If you are looking for a plant that will be a talking point and entertain children of all ages this could be the one for you!
It is a clump forming evergreen rush that is grown for its stems which corkscrew in a most endearing way, each with a different amount of twirl so as it looks like a plant that has had a very bad perm!
Grow it in an ornamental pot sitting in a permanent saucer of water in a sunny spot and wait for the questions. It will like all self respecting bog plants also grow well in permanently damp clay on the edge of a pond or even partially sunk into the water.
Grow it in quantity simply by dividing a large clump at any time of the year and clean out dead stems every so often to keep it looking at its best.
