Ostřice (carex) je velmi obsáhlý rod stálezelených i opadavých trav, které spojuje významná vlastnost, jež jim dala botanické jméno a promítla se i do češtiny – okraje jejich listů jsou totiž více či méně ostré, podobně jako precizně nařezané listy kancelářského papíru. Ostřic je více než 1500 druhů (moderní prameny hovoří již o téměř 2000) a objevují se prakticky ve všech klimatických zónách od horkých tropů až po arktické oblasti, kde se mimochodem jedná o jednu z nejvýznamnějších skupin flóry, která je schopná přežít v tak nehostinných podmínkách. Liší se velikostí, barvou, šířkou listu, kvetením i stylem růstu – některé jsou trsovité, jiné se rozrůstají a dokážou vytvořit nepropustný půdní pokryv. Většina ostřic včetně těch, které jsou domácí i u nás, se přirozeně nachází na vlhkých až mokrých stanovištích, což je vcelku paradox, protože mnoho z nich výborně zvládá dlouhodobé sucho, pokud nejsou na osluněné lokalitě.
Japanese grass sedge is an evergreen species of ornamental grass native to central and southern Japan. Ice Dance is one of its key varieties proved by decades of cultivation. It boasts rather wide (up to 1.5 cm) leaf blades that are erect, stiff, leathery, sharp, 30-40 cm long, deep green in the centre and off-white at margins. From mid to late spring appear inconspicuous flowers on thin stems. Ice Dance forms dense and compact, symmetrical clumps which slowly spread forming a nice ground cover, yet not being invasive.
Evergreen sedges cultivated in zones 4 to 8 are usually low-maintenance plants requiring no extra care once established. Though, removing its foliage after winter will enhance brand new, fresh green growths if old leaves are unsightly. Otherwise, they are often used for landscapes where neglect is expected. They prefer part shade to shade but grow in full sun, too, if regularly watered. Avoid extremes of wet and dry conditions. Ice Dance prefers moist to wet ground, humus-rich soil, and semi-shade or deep shade, especially in winter in borderline locations of its hardiness. It can take long spells of summer drought once established. Fully hardy to -29 °C (USDA zone 5) and suitable for outdoor pots.
