The carex, or sedge, is a perennial herb belonging to a genus that has hundreds of species, originating in the temperate areas of the globe; C. elata is native to Europe and Central Asia. It has the appearance of a thick tuft of grass, with 40-50 cm long, arched, bright green leaves; with time it tends to become ground cover, forming numerous round cushions; in spring it produces long triangular section stems, erect, which carry spike inflorescences made up of small dark flowers, which will give way to numerous fertile seeds. There are variegated cultivars or with yellowish green stems. C. grayi has leaves similar to Carex elata, and in summer produces numerous characteristic star-shaped inflorescences.
To obtain the best possible growth for this plant, it is good to plant the carex elata in a bright and sunny area; sedges develop equally well even in partial shade, provided they can receive a few hours of direct light a day. They do not fear the winter cold and the summer heat, adapting without problems to the different seasonal temperatures.
The specimens belonging to this particular variety need to be placed on the banks of rivers and ponds, with their roots sinking in constantly moist soil; the plants develop very well even in low ponds, completely immersed in water up to the collar of the stems. It can also be grown in pots or in open ground, but in these cases it will need abundant and regular watering, with the foresight to check that in the container there is always a high degree of humidity, given that the sedge does not bear drought and it is irreparably ruined quickly.
